Hey man what’s up with all the vertical!?....
I’m just kidding that’s nice!

It did qualify as a screamer group but it is still three times the size of what Bart shot last year......

My personal best is 10 shot 5” at 1000. I’m hoping to do better this year. I took a few years off so probably not! I don’t think I’ve ever shot that well at 600 but then I’ve never competed at 600. My hats off to you that’s nice shooting! Now I have shot under 5” but at my range in competition I have not.

Thank you sir!.... wished I was more on par with some of my friends over there, wayyyy smaller than mine but ya know I just enjoy being with like minded great people and away from work!5" 10-shot groups at 1000 are excellent!
If you're fireforming improved cases, why not send them to a service like DJ's? Zero barrel wear.
I've read many accounts of competitive shooters shooting in matches with bullets heavily jammed to (fire)form...
When I first got my Dasher, the smith recommended the false shoulder method and a bullet. I shot a number of 300 yard matches fire forming Dasher cases from 6BR’s.
The reason he recommended a false shoulder over just a jam was in his opinion, the firing pin impact would move the case forward, ever so slightly, and upon firing would force the case head against the bolt face, potentially stretching the case, weakening that area, which in time could lead to head separation. Whether correct or not, using the false shoulder method has allowed me to reload those cases over a dozen times and still going without a single case failure. Take it for what it is.
However, now it’s just the COW method, still with a false shoulder of course.
I approach the process similarly, and have been more than satisfied so far. Granted this is with only 1 example, but should be founded on logic (as opposed to false logic):Yes I've always used rifle powders to form AI cases. With bullets. I've posted several times about this. Don't understand why people screw around with fillers unless maybe they're just horny to make something go bang. But it's real simple, and I'm talking about IMPROVED cartridges. The improved chamber is larger than a std. chamber, so when firing a standard case in an Improved chamber the thing expands quite a bit. A max load for the std. case is a light load when shot in an improved chamber. Start with the accuracy load for the std. cartridge and do a load work up like with any other cartridge. Stop at the most accurate. And of course be watching for overpressure. The accuracy load will be somewhere between a max load for the std. chambering and what you'll be shooting with formed brass. That fireforming load will be faster than standard and just as accurate. So it's a working load that's faster and with the bonus of producing a perfectly/completely formed Improved case. A total win-win, there's no downside.
Yeah. I bought a used 6 Dasher barrel off a fellow on this site to fire form my cases. It turned out the fire forming barrel was more accurate than the one I was fire forming for. Seems one problem leads to another....... Hydroforming or a brass service sounds good to me. Running out of sacrificial barrels.For me it's not a matter of shooting up bullets. It's using up 200 rounds of barrel life and getting no useful info in return when it comes to forming for an AI competition rifle.
My dasher fireform barrel has around 15,000rds on it. Couldnt tell you how good it shoots nor the last time it was cleanedYeah.
