    6gt

    Most are using 6gt for competition or at least a similar practical type shooting. Jamming and such increases the chance of sticking a bullet at an inopportune time. So most won’t even test it. I’m sure you’ll find some jams that shoot well. Most will also be using around a 26” barrel. But I’ve...

    New M-BRACE Scope Mount $279 from American Rifle Company

    First match with the m-brace. Was using m10 rings before. Went with the mount due to simplicity and to get 1.5”. I like to keep my head as vertical as possible.

    Expander Mandrel and FL Sizing Die Question

    The more you size the neck down, the larger mandrel you’ll need to get the desired neck ID For example, you won’t be able to say size the neck .003 smaller than you want, then another piece .001 smaller, and use the same size mandrel for each to get the desired end result. The least amount of...

    What is the purpose of neck tension?

    In theory, neck “tension” only matters as long as it’s consistent. When the release is not consistent, your velocity numbers will be more variable. What happens when most people say they found that “my rifle likes .003 neck tension”……what has really happened is the process they used to get that...

    Needing Sage Advice on a Season of Failed Load Development

    “Velocity nodes” are simply a misunderstanding of flat waterlines (positive compensation and such) when chronographs became popular. Positive compensation is a whole other discussion. Powder charges don’t magically have substantially less velocity increase randomly in the middle of standard...

    Kestrel Meters Ballistics Official Thread

    @Kestrel Ballistics Mounted a HUD to my spotting/laser setup. The idea being the kestrel is in a wind vane full time feeding wind data and such. I have two questions: Will a laser (terrapin-x in this case) update any target except target A? For example, when I’m in the large font target card...

    What is the purpose of neck tension?

    Just chiming in that when you set the jump at “touching lands” that will change some things. The primary resistance is now always the lands. So generally speaking, you should see better results with less interference fit and/or friction (as it’s already been pointed, we were dealing with many...

    Bags, bags and moar bags

    One of the biggest things we have to correct in classes is the improper use of fortune cookie/gamechangers in the rear. They will work, but I’d say probably 80% of students we see are not using them properly. Most drop in on the ground or bench, sit the rifle on it, and and then work around...

    Not seeing anything

    He absolutely doesn’t know anything about “flat spots.” You can have a big name and mean well and be absolutely and completely wrong. Do a velocity flat spot ladder test 10 times. You won’t get 10 consistent “flat spots.” If you do, and it continues to be consistent, researchers at MIT and...

    Trigger hand placement question.

    In person instruction is going to be your best option. Also, you can’t really use your current results or your current comfort level as a gauge of what does and doesn’t work. “I simply shoot a better group” yet both grips would likely get an overhaul, so it doesn’t matter and you’ll come out...

    Wind flag contradicting mirrage

    As a new shooter, I’d focus on my wind calls at the shooter position, as it’s the most important. Then, once comfortably making good calls, advance to reading wind between shooter and target. If you can’t effectively read wind at shooter location, you won’t read it anywhere else.

    Wind flag contradicting mirrage

    When shooting fairly close (inside 1k), generally speaking this is the order of importance of wind: 1: at shooter 2: midway 3: at target With the target being far, far less important. The reason so many use things like dust direction when they miss, or from the spawling from an impact is...

    Find a node or pick a velocity and then tune seating depth

    I challenge anyone to post any long term, high confidence data that shows “nodes” act in the way this post describes. And if you (anyone) can produce such data, I promise AB will be happy to have you out to shoot several days and several thousand rounds over their doppler to prove your method...

    Arbor Press with gauge question

    As to the OP, force gauges and such are literally comparators, just like your calipers with inserts for headspace and seating. For the most part, they don’t help you make better ammo, they allow you to make consistent ammo. You will need to do the testing yourself, find what works for you and...

    Arbor Press with gauge question

    This information is incorrect. You can absolutely have two or more distinct numbers and still have ammo that shoots fine. Here’s examples of different kinds of seating force curves. They all shoot well. There is thus far zero evidence or data that suggests a fluid gain is better then a gain...

    Ruger Precision Rimfire

    Stop giving people false hope. You did this a while back with your cold bore claims with centerfire that don’t hold up to hit probability math. You also just made a post about how hard a time you have hitting 20” plate @ 500yds. So, make up your mind. A Ruger RPRR is a $400 rifle that acts...

    Might belong in the ELR forum, but here goes..

    Also, @ 300yds, if you keep track of data long term (like actually track every round), you won’t be under 2moa long term with Rimfire. Just doesn’t happen. AB’s doppler radar is already showing how unstable Rimfire is at that distance.

    Might belong in the ELR forum, but here goes..

    ELR is inherently low hit % because of math. Plain and simple. At those distances, many times the target is smaller than your ES needs for 100% hit probability sans wind, lighting, etc. So, your hit probability was already pretty low (depending) before the angle of approach vs angle of target...
