Im finding some dry fire / moving dry fire drills the morning of a match is making a difference. Also, going to a safe area for dry fire immediately before shooting helps. If dry fire at home is what takes the greats to the next level, why couldnt it be good warm up before live fire?

If you are using a blowback 9mm AR your best option is tuning ammo. Obviously reloading is your friend. next best is buying a small box of a dozen or so commercial brands and start measuring chrono and watching dot bounce. you probably wont find much 9mm that is friendly on recoil from a 16in barrel. or say screw it, get a great comp and exercise it with some 170pf 9mm major and see if hot ammo gets you anywhere.

Yes, that is what I said on August 7th...

As a newly minted GM I'll throw in my 2 cents. Per the original question, most GM's get there by shooting classifiers, as others stated, few make it to GM via match bump. Your only path to GM via match bump is Nationals. Regarding classifiers: 1. I've practiced them ahead of time, sometimes it has worked out for me, others it hasn't. 2. Regarding classifier re-shoots. I've re-shot them for various reasons. Gun malfunction. Recently I had a gear malfunction. I've simply shot poorly (nearly zeroing) and reshot. It's all reflected in the classification record. Some have been GM scores, some haven't. Paid classifier re-shoots did not count toward match score. 3. I've also shot enough classifiers without practicing ahead of time, without re-shoots, to still earn a 95%+ average. I'm also one of those PCC guys, of which I've heard is the "easy" division. Maybe it is, maybe it isn't, clearly HHF's needed to be updated (my 95%+ average is post adjusted HHF's). I've been shooting PCC for just over a year, my goal was to make A this year. With a lot of live fire practice, and immense dry fire / simulated practice (with a SIRT rifle), I climbed my way there. Personally I feel I have mastered reloads, transitions, splits, and managing engaging near / far targets, open / hard cover and no shoot targets. Fundamental skills that translate to "normal" match stages. I have NOT mastered moving while shooting, executing the best stage plan, and minimizing movements. Ultimately, I do not think classifiers test the full skill set necessary to be 95% or above in a match. I feel I have half of the full skill set I would personally like to possess. Next year I'll work on what is missing. My goal this year is to finish out a 100% classification average, I'm 1 classifier away. My highest classifier percentage is 125% (reflects as 100% in the record), highest classifier HF is 17.1, I doubt those numbers occur very often. Yes. I'm probably a "paper" GM, there is still a LOT for me to improve on. I haven't gone to many bigger matches due to travel / time constraints. Regardless, I find it unlikely that most could achieve 95%+ without a lot of practice and ability.

Used two goliath mags in competition tonight. Ran them both completely full (51rnds). Had 0 malfunctions, everything cycled and fed flawless. Even shot a 100.5% on nueve el pres. Limited data point, nevertheless, ran great in the JP.

Recieved email confirmation with tracking numbers. Boxes showed up today!

The JP gmr-15 has a full diameter chamfer as well. Reliable feeding with blow back AR-9's seem to be a well tuned combination of feed chamfer / feed ramp married with magazine presentation angle and depth. One of my AR9 builds only works with glock mags and round nose bullets. So far my JP has worked with everything.

Ordered my evolution pro in August, will recieve delivery tomorrow. Seems shipments are going out!

Just assembled 2 goliath mags. They load to 51rnds with my 1.13" reloads just fine. They insert with the gun in bolt lock, I wasnt able to insert the mag in the gun with bolt closed. Manually cycled a few rounds in the JP. Will run it in competition tomorrow and report back.

Agreed. Surprised powder drops would be worse with the evo. I also never get this tight variation out of my 650. I'm consistantly +-0.2gr albeit, with mixed cases.

Are you using the same head stamp brass?

See this thread as well as the picture at the bottom of the page

Very cool. Based on your data it appears carry optics hasnt pulled away much from production when it comes to HHF and is ripe for more GMs.

I'll throw a vote in for the MRO as well. I've done very well with it. Really you want something reliable, bright enough, positioned at the correct height and location on the rail so that you dont have to think about holdovers much.

You will no question have less issues running 2 passes. It will work with 1 pass, you will be stopping more often to deal with issues, likely have more powder spillage opportunities, etc. If you fully process the brass, then move to loading with case lube, it is darn near close to loading with brand new brass.

Ahh ok. Havent started loading coated bullets yet, good to know. Glad to see your machine running smooth.

Looks great! Is it just me or are you expanding more than you need before the bullet feeder? On my 650 with the mr bullet feeder expander, the case expansion is minimal.

Ditto. You want to roll first. Rolling often simply moves the problematic buldge higher on the case so it can be corrected during sizing. If you size first, then roll, you may end up "un-sizing" the top of the brass requiring yet another sizing pass to bring the case back to spec. Best order is to roll then size.

I have a suppressed kimber 1911 in 45acp. I love it. The real question is, why wouldn't you suppress it?! Didn't buy an after market barrel. My kimber came threaded....

Pre-ordered 2 of them. Will report back once I put em through some rounds.

I don't visually inspect everything. I do case gauge everything, I flip the case gauge over and let all the rounds sit facing up on a flat surface looking for wobble as a high primer check.

Would alphas per second be a better metric? 82% alphas here, shooting minor

I'm in the same boat. Tightened the clutch and I run 800 rounds of 9mm regularly without issue.

I wasnt given an option to pre-order it. I was told it was still under development with maybe an end of year release date, nothing firm.
