Just some good old fashioned police work

So no one was killed , which is amazing .

These Maine police had a photo and a name and an address and a place of employment for the suspect they were looking for , and went heavy- full kit and rifles to a high school and arrested the wrong person, who’s name and photo and address did not match.
And the reason for. Swat raid on school grounds - stolen shoes and cologne. The person they were actually looking for was arrested days later at his place of employment without issue .


The kid who delivered pizza gets it right every time - and he never has a photo.

So maybe stealing shoes is a capital crime in Maine , if it’s bad enough to send SWAT to a high school you’d think they match the person with the photo before making their move . But they did get it on the second try so 50/50. And no one died so I guess not too bad .

Our friends from the Philippines are back

I was really upset. Heard other’s were getting their notices that if they didn’t pay their traffic fines, we would get our licenses suspended and reported to the toll booth.

Finally today I got mine. I forwarded them to the Nigerian prince who is giving me ten million dollars if I let him use my bank account to hide his billions. I’m sure he can take care of it all.

So, gotta run, I got a letter from an out of state finance company that they are going to loan me $800,000 on my house as a second mortgage with no down payment, just sign up and get the cash. No payment required until August of 2027.

Serious. When our home was valued in the middle 200,000’s (it’s only a 1500 sq ft cottage.) I got an offer for a loan by one of these mail out loan agencies that they would loan us $450,000.00 on our home, sight unseen.

Guess I better get my ticket paid right now. :).

Gunsmithing Omega 300 end cap brake adapter

I recently designed an endcap adapter that will allow mounting of any 5/8-24 muzzle brake to the front of an Omega 300 suppressor. I had it machined from 416 stainless and it turned out pretty awesome. Because of the long lead times for the X factor front brakes, I am considering doing a bulk purchase and wanted to see if anyone would be interested. Example area 419 brake mounted photo attached. I will need to dial in the thread length a little better, but overall, it looks like it will work well.

Steel Mill explosion, Western PA

I went to college in Wheeling WV from 1981-85 and many of the students at that small college were from the nearby region, Ohio River valley, coal and steel country. Many were 1st generation in college because in their mill/factory town, de-industrialization had caused closures or cutbacks in workers, leaving these youngsters without a local job prospect. So they went to college instead.

They would tell us from big city areas like DC, Phila, Baltimore what the economy was like in the eastern Rust Belt, how their families survived on blue collar incomes, etc.

Earlier today I saw this news story about a steel mill coke plant in Clairton PA.

Optics Gen 3 Razor 1-10

Sold a Leupold MK5 3-18 a while back and am kicking myself. Picked up this Razor for an aborted build and now it's time to move it... again. Old eyes need that parallax adjustment.
Tried selling a few months back but someone scammed the gentleman who agreed to buy and now am hesitant to try again. Rest assured I'll run the gamut to make sure that doesn't happen again.
If someone wants to trade for a similarly priced Leupold Mk5 +/- a few dollars that'd be great. Otherwise original deal stands
$1500 shipped.

Thanks

Semi custom or full custom bolt gun?

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.

Advice needed for 2017 Buick Enclave repairs

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?

So I went to Grok to Dissect Gravity Ballistics

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.

The waterline was magic to GROK his got it right away

IMG_1193.JPG


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.

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.

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.

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

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).

Reads like I wrote it, but it was GROK looking at the data and comparing it...
