A new shooter should use Doubles Drill as a Grip and Vision drill first and foremost. Improving those will improve scores. It's not until further along the learning curve that that working through how far out you can do predictive shooting is a big time saver. Mix in some Accelerator drills so you aren't just blapping away at one target at the same distance.

Newer DPPs seem to be a lot more robust than the old ones.

The trick people often miss about Doubles is you need to call both shots in the pair, even though you shoot the second shot without taking the time to confirm the sights.

Yeah, N320 was one of the gold standards. Some people (BE included) played around with Clays but it was very twitchy and unless loaded long could easily blow cases.

20 years ago with 38 Supercomp I shot 9.6 of 3N38 under a 121gr HAP from a 16" barrel Mech-Tech. 1623 FPS for 196 PF. Same load did 1392 in a 5" comp gun at the same time. 7.6gr 7625 and a 124 gr MG JHP (My Open Major load at the time) went 1357 fps pistol & 1562 in the rifle. Notes say the brass did not look good after the experience so after that I desisted except for minor loads.

I did a CZ S2 with a non-carbide Clymer throater and it worked, but it was tedious and the reamer took a beating. I had to regrind the pilot to the CZ land diameter so it would even fit, so in toto, one star, would not recommend. Most SAAMI 9x19 reamers will fix the short throat if you can rent one or find a gunsmith with a carbide reamer and are careful not to enlarge the chamber while you're at it. You may need a smaller pilot if it's a piloted reamer. If you don't have a nearby smith or the inclination to do it for the education of it, you may just want to send it to someone that does CZ barrel reaming as they've got the tooling, setup and know how to do them efficiently.

Why should every other club match have to paint because of your issue? Wouldn't it be easier for the match to say "paint every 4 shooters" themselves? That said I like painting between shooters, but most don't want to bother and I'd rather have matches with no painting than no matches.

US IPSC Nats last weekend had a weak-hand-only gun-in-box start. Couldn't even touch the pistol strong hand to pick it up. That sort of thing is way more common in IPSC than USPSA.

Edges in 9mm aren't super common (vast majority were in .40) but they're out there. I like mine for LO, although I may go with a lighter slide next time around.

Most likely the problem is going to come from the contour of the grip at the mag catch side. Many newer ones are thicker there because the old metal copies of plastic grips would crack there. Too thick and the right-side mechanism won't work well.

There's a pic rail cut into where you normally tap for the scope mount. You could weld that up or silver solder a plate over it or something if you wanted, but it adds work.

Nice. Don't be afraid of the crimp!

Ehh. we had a lot of casual shooters at the A4 SC a couple months ago, and some ROs that thought telling people to move on Showdown might be coaching... those two need WSBs, the other can just be "shoot P1-P4 in any order, then SP"

I asked Troy at NROI before I RM-ed the A4 Steel Match but there weren't any (supposedly that's in process of being fixed), so I made my own basic versions.

I use a lot of 231 in 9mm, although mostly with 125gr jacketed bullets. For 147's I'd just pick a lead bullet starting load that looks about right, see where it chronos and adjust from there.
