I’m debating with myself whether or not there are good enough factory barreled actions out there or if I should just wait longer to save up for a full custom. For context I’m still building a 6mm arc bolt gun that’s mainly just for long range target shooting but I’ll use it to hunt as well. I want a longer barrel to take full advantage of the velocity I can get out of the pretty moderate cartridge. I plan on shooting the projectiles in the 105-110 range. I have a lot of cfe 223 that isn’t being used. Since it is a pretty light recoiling cartridge I can get a pretty light system I plan on using a brake simply because I just can’t afford a suppressor yet. I really like the idea of the Christensen mpr but I know christensen has had a lot of issues recently and I don’t like the 16 inch barrel, maybe just buy the bare chassis? I had a Howa mini action in 6 arc I was in love with but unfortunately had to part ways with because of financial issues. On a somewhat related note does anyone know of any other mini length custom actions out there I can’t find diddly on if another than Howa currently makes one.

Barely used, but used. I will break this up if no interest for the whole package.

How does the lasering line up with your action?

Noticed a significant shake in the steering wheel at speeds 60 mph and above. I am going to replace the brakes and rotros but wanted to take it to the dealer to check everything out since I plan on driving this for at least another 2-4 years. Here's their diagnosis and quote:
1. Steering gear w/ alignment - $3,253.27
2. Both rear lower control arm bushings - $967.43
3. Front & rear brake + rotors - $1,331.63 (I'm gonna do this so maybe $500)
4. Front flex pipe (starting to crack) - $1,400.30

I think this estimate is ridiculous. How complicated would it be to DIY the steering gear (not the alignment), bushings, and flex pipe?

Woke up early as usual the other day and I decided to query GROK about Gravity Ballistics,

This X-Factor method you've described is an empirical, recursive multiplier approach to estimating bullet drop compensation (in mils) for each successive 100-yard increment beyond 300 yards. It essentially extrapolates the total elevation adjustment needed at longer ranges based on the value at the previous range, accounting for the non-linear nature of bullet trajectory due to gravity and air resistance. This can be useful as a quick field estimation tool without needing software, assuming you have confirmed data at 300 yards (e.g., from chronograph, rangefinder, and actual shooting).

Had to educate him a bit, and then when talking the Gun # he did reference the site over the years. Now if you go back to my posts with Bryan Litz, him and I arguing over ballistics, SD, CE, etc, GROK Likes the Pesja information better than his information. It relies heavily on Pesja which is where "I" started versus the Other Guys out there.

Pejsa Approximation (Closed-Form Alternative)**:

- A simplified analytical model for drag: Velocity \( v(x) = v_0 \left( 1 - \frac{x}{3F} \right)^{3} \) for mid-range, where \( F \) is the "retardation distance" \( F = \frac{1000 \times BC}{\sqrt{d}} \) (d = bullet diameter in inches; adjusted for slope factor ~0.5 for most rifles).

- Time of flight \( t = \int_0^r \frac{dr}{v(r)} \), then drop \( h \approx \frac{1}{2} g t^2 \cos(\alpha) \) (where \( \alpha \) is initial launch angle for zero).

- To compute: First find \( F \) (e.g., for .308 168gr BC 0.45, F ~5000 yards), then integrate or use Pejsa's tables/formulas for drop.

- Comparison: Pejsa closely matches full drag models (within 5% at 1000 yards) without integration, making it better than vacuum but more complex than your multipliers. Your X-Factor ratios decrease similarly to Pejsa's effective drag adjustment (slowing ratios as range increases), but Pejsa is tunable via BC for better accuracy across loads.

I have always said, Pesja, but Bryan was a McCoy guy... Pesja is better and dismisses SD, CE for mechanical fixes like I have stated over and over ... Me and Grok are friends.





Goes on to explain how a lot of the early work was between 400 and 700 yards and then extrapolated out to distance, much like shooting a bullet at 300 yards subsonic and attaching it to a supersonic recording to estimate the changes. You need to do it right, as I have said over and over....

When you incorporate corrections for center using a waterline—a horizontal reference line marked on the target to ensure a level scope reticle, consistent point of aim (POA), and precise measurement of point of impact (POI) deviations—the process fundamentally shifts how the X-Factor multipliers are applied. This method emphasizes truing your rifle's dope (elevation data) at each 100-yard increment: you aim at the waterline, shoot a group, measure the vertical offset (drop in mils), adjust your scope turret to center the POI on the waterline (making POA = POI at that range), record the adjustment amount, then repeat at the next range. The waterline helps minimize errors from cant (scope tilt) or inconsistent aiming, as any cant would cause lateral walk-off in impacts when dialing elevation.

Click to expand...

The waterline was magic to GROK his got it right away

How This Affects the X-Factor Math

The original X-Factor method uses multipliers to predict **total** drop compensation in mils from a fixed zero (e.g., 100 yards) to longer ranges. Mathematically, if \( D_r \) is the total mils at range \( r \) yards, then \( D_{r+100} = D_r \times M \), where \( M \) is the X-Factor for that step (e.g., 1.75 for 300 to 400).

By adjusting to center at each range, you're effectively re-zeroing the rifle at that distance. This means:

- The "data in mils" you record and use for the next prediction is now the **incremental** adjustment (the additional mils dialed to center from the previous zero), not the cumulative total.

- The original multipliers (1.75, 1.45, etc.) no longer apply directly because they were designed for scaling totals, which grow quadratically with range (adjusted for drag). Incrementals, however, scale more linearly with range as the bullet slows, increasing drop per 100 yards by a smaller, more constant ratio.

Click to expand...

The key is the aiming point, it's not a 1 Mil variation because of the target height, I often demonstrate it as the question of group center from a low number of shots on the plate. We get it, we don't need 50 rounds to determine out average, but we need a few. I took this from Gunsite, it's a very good visual, and I use it a lot.

Accuracy Improvement**: Using the waterline and centering each time "trues" your data empirically, reducing errors from cant (~0.1–0.5 mils at 1000 yards) or mismeasurement. However, the adapted X-Factor is still an approximation—errors can accumulate (e.g., ±0.05 mils per step, or ~18 inches at 1000 yards total). It ignores wind, spin drift, or atmospherics, so combine with a full ballistic app for refinement.

- **Deriving Your Own Multipliers**: Shoot and true at 300–500 yards to find initial \( M' \), then extrapolate. Mathematically: If you have two increments, \( M' = I_{next} / I_{current} \); average over shots for your specific setup.

This adapted approach makes the X-Factor more field-practical for building custom dope but requires redefining it for increments. If you provide actual shot data (e.g., measured mils at 300–400), I can compute tailored ratios.

Click to expand...

Without Truing other software is considered "Lost" in noise...

**Altitude-Adjusted Models**:


- Even with DA correction, the model underestimates by ~1.75 mils at 1000 yards. This suggests:


- **Formula Limitations**: Point-mass models assume a simplified drag curve (G1/G7 tables). Real-world drag varies with bullet shape, spin decay, and transonic effects (6 ARC goes subsonic ~900–1000 yards at 2750 fps), which trueing captures but models may not fully replicate.


- **Individual Rifle Variability**: Barrel twist (1:7.5" typical for 6 ARC), powder charge, or bullet lot can alter performance. Your trued data reflects this reality.





3. **Empirical vs. Theoretical**:

- Your waterline-trued data is more accurate for your specific setup than any unadjusted formula. It aligns with the principle that field-verified dope (e.g., via shooting to center) outperforms theoretical predictions when conditions deviate (altitude, MV, BC).

- Other formulas (e.g., Pejsa, vacuum approximations) would fare worse without trueing. Pejsa, while tunable, requires exact BC and MV to match, and vacuum models (quadratic drop) overestimate early and underestimate late due to ignoring drag.

Click to expand...

What Grok did suggest to me, changing the X-Factor at 1000 yards from 1.22 to 1.18, now this may be due to my home range being in Colorado with a DA of 7000 ft during the collection of data, but really modifying our average from 1.22 to 1.18 is pretty amazing to consider.

This was the real difference with Gravity Ballistics, we collected more real world data than anyone, period. We collected every shooter's data in Alaska for 3 classes in June and 3 classes in July. That was 16 x 3, x3 worth of data to drop into a spreadsheet in order to find an average effect for gravity. Marc was on top of it.

Implications for Other Ballistic Formulas

- **Standard Sea-Level Models**: Without altitude (7000 ft DA) and sight height (2.8"), these underestimate drop significantly (e.g., 7.20 mils at 1000 yards vs. 8.5 mils), off by ~1.3 mils (~47 inches). Your trued data underscores the need for environmental and setup-specific inputs.

- **Altitude-Adjusted Models**: Even with DA and 2.8" sight height, the model lags by 1.20 mils at 1000 yards. This suggests:

- **Drag Model Limits**: G7 tables may not perfectly match your bullet’s transonic behavior. Doppler-tested BCs or custom drag curves (e.g., via Hornady 4DOF) could close the gap.

- **Rifle-Specific Factors**: Barrel twist (1:7.5" typical), powder type, or fouling could alter performance, captured only by trueing

Click to expand...

Note, Grok compared the other models I did not ask him too, he was using known data found online and then comparing it based on the data I provided. When I gave him completely details it go better and better as far as our methods.

Accuracy of Trued Data**: With 2.8" sight height, your trued data is highly reliable for your 6 ARC at 7000 ft DA and 85°F, with errors vs. the model dropping to 0.00–1.20 mils. The 1.20 mils (43.2 inches) at 1000 yards is usable for field estimates but requires precision adjustment for target work.

- **Implications for Other Formulas**:

- Sea-level models need altitude, temperature, and sight height to avoid ~1–1.5 mils error at 1000 yards.
- Adjusted models still miss by ~1.2 mils, indicating the value of trueing to capture real-world drag and setup nuances.
- The X-Factor method, when calibrated to your 300-yard start (1.0 mils), matches well, offering a practical field tool if you accept a ~0.2–0.3 mil fine-tune at long range.

- **Recommendation**: Use your trued data as the baseline. Input 2775 fps, 0.270 G7 BC, 2.8" sight height, and 7000 ft DA/85°F into a ballistic app (e.g., Applied Ballistics) to confirm. Test a lower BC (e.g., 0.250 G7) or recheck MV over a longer string to align the 1000-yard drop. For quick use, adapt X-Factor with your incremental ratios (e.g., 1.8/1.0 = 1.8 for 400, adjust thereafter).

Factory Bergara heavy barreled action B14R in 22LR sitting in an MPA Hybrid chassis with competition rails and steel weights. The BA has less than 500 rounds through it. I set this up for my daughter to shoot when the weather was not conducive to her 10/22 Kidd build. Happy to share chrono results (eley team and semi auto Benchrest precision were incredible).

The chassis has seen some wear, but is functionally fine. It looks a little off without the rear bag rider, but that weight causes it not to balance. It does balance without the bag rider just fine.

Hello all,

I have the ugly annealer, which does the job. However, sometimes the torch tip spits and drips fluid, runs an orange flame, then goes out. It’s very annoying that I can’t get a batch of brass done without this happening. I’ve replaced the tip 4 times and thought I had it working with this one. I run a hose from the camping propane tank to the mounted pencil tip. Does anyone know what’s causing this and how to stop it? I usually can’t get it to relight correctly after it goes out. I can hear propane in the bottle when I shake it (gently) so I don’t think it’s out of gas. Any help is appreciated!

I bought a bunch of fired Winchester 308 WIN brass at a gun show in town and it's shoulder has been set back nearly 2 tenths more than new brass that it have for comparison. I picked up 350 of these for really cheap! Now I know why.

What does a guy do with this? Trash it? I'm not set up to fire form, and the components, powder, and time is kinda cost prohibitive.

Fantastic Condition, like new!

I am down to my last 400 of the AMP 225gr BTHPs. I jump online to order more.....discontinued! This was one of the best 308 diameter bullets I ever tried. They are way more accurate (for me) than the ELDs and they knock the soul loose from deer and bear.

Anyone have a recommendation of a similar projetile?

The Wyoming legislature pretty much dumped gun free zones effective July 1, 2025. If a person with a concealed firearm permit can now carry concealed (no open carry) in schools from K-post secondary, at athletic events, board meetings, etc. The exception is if a person is a student K-12 at any school in the state, they can't carry in any K-12 school.

Schools can not deny anyone the ability to carry concealed if they have a permit. In fact, to do so is a misdemeanor crime. The legislature also gave schools the right to set minimum training standards for employees, and for school volunteers. School districts can also set standards for for those who provide instruction to their staff and volunteers. If the school doesn't develop standards, employees and volunteers would only need the CWP. Schools statewide have been adopting standards at a jack rabbit's pace.

The minimum requirements set by the state are:

• An initial course that includes at least 16 hours of live fire handgun training, and eight hours of “scenario-based training using nonlethal training,” firearms, and ammunition; and
• Annual firearm qualification and documented recurrent training of not less than 12 hours with an approved instructor.

To date, the district requiring the most training is the high school where I graduated in Laramie, aka "baby Boulder". Their policy is 11 pages long. In a nutshell:

A. Prior to carrying a firearm on School District property, the employee or volunteer shall complete an initial training course comprised of not less than forty-seven (47) hours of live fire handgun training, and sixteen (16) hours of scenario-based training using nonlethal training, firearms, and ammunition.
B. Thereafter, employees and volunteers shall receive recurrent training of not less than eighteen (18) hours each year with an approved instructor.

I suppose that doesn't look too bad on the surface. The problem arises when one looks at other requirements that include de-escalation/hostage negotiations, updates to state and federal firearm and self-defense laws, case studies and legal reviews of use-of-force incidents in schools, participation in joint drills with local police, trauma and emergency medical response training, and the list goes on and on. Oh, the district has also defined the requirements for the trainers. None of the trainers at the Wyoming Law Enforcement Academy meet the requirements, and the curriculum offered at WLEA misses the mark by a longshot.

The Albany County School Board (Laramie) has made it clear in their position statement that, "Albany County School District No. 1 strongly opposes the Legislature’s repeal of gun free zones3 in K-12 public schools. The intro to their policy reads "Guns simply have no place in our schools and will not make them safer for employees and students". The district seems to be proud of themselves for taking every step possible to make it impossible for a teacher to pack heat. In fact, a teacher can be fired for carrying a gun to a football game, but I can stand next to that teacher with a concealed firearm. If they say shit to me they could get hit with a citation that carries a potential penalty of a year in prison, a $2000.00 fine, or both. Of course, the liberal assed County Attorney would likely never prosecute the school district.

Jackson Wyoming is also pushing back against the abolishment of gun free zones. Just like Albany County, their requirements are so difficult that it's impossible for an employee to meet them. Jackson even went one step further, if an employee met the requirements they would need to sign a waiver absolving the district and their insurance carrier from any liability resulting from the use of a gun. While I am ranting, the legislature also passed a law requiring biological boys to use the "boys" room, and biological girls to use the "girls" room. A quote from the superintendent in Jackson, "Ninety percent of this is just nonsense that this Legislature has decided to inflict on schools,” Mead said. “I don’t think our kids should have to live with weapons. I don’t think they should have to worry about which bathroom they go to.”

Any of you want to guess what Teton County and Albany County have in common?
