ChuckS

From my experience, it only takes a few hours of exposure per week to cause this problem.

I know a guy...

IPSC? NOT APPROVED: 17TB, 18, 24, 25, 28, 34, 35, 41, 42, Pro, L, C models

Check the bottom edge of the bolt face. If it is sharp, it can drag the "next" round forward so it drags on the mag well if you try and drop the mag. This has been a traditional problem with CZs and I see no reason that the problem could be realized with any slide. A very slight bevel on the edge fixed it for me. Good Luck, ChuckS

I have lost only one mag in the last 5 years (~35K lightweight ) and that was due to the weld up the back of the tube splitting and causing drag on the aft end of the follower. About 27K of that was with a non-ramped barrel. For the record: NFA lower, Alpha Sports un-ramped barrel, short stroked uppers. Stock tubes with Grams springs and followers.

"Never get out of the boat"... Good luck with your journey!

Plumbing. The tool of Satan...

No problem. I forget the details but I saw that you could move the safety with the hammer down on a shadow (or maybe an SP-01) that had been tweaked. Either CGW, CZC or both. That was 10 or more years ago so it is kinda fuzzy

I researched this when the CZs started getting real popular. I discovered this in the TS2 manual: "Due to the special adjustment of the trigger mechanism it is possible to rotate the safety to a "SAFE" position, even when the hammer is on the safety notch, or leaning against the firing pin stop. However, it is not recommended that the safety be engaged while in this state, because forced cocking of the hammer could damage the trigger mechanism. "

Excellent choice!

It was discussed in 1976... IPSC_1976_Columbia_Conference_Minutes.pdf

The calculator is primer friendly! Just choose a division and put in any hit factor. The calculator will tell you the percentage for that hit factor and will also show the minimum HFs needed for each class. Then you can play with points and time to see what you need for the classification you are interested in.

The classifier calculator on the USPSA web site will allow you to see this sort of stuff

Funny thing is that I had good luck with Frontier 121's until my source retired. It was MG 121 IFPs after that.

Less picky than my strict criteria of "not stepped" and "not cracked" that I used for my 2011?

I was out there for the Red Rock Rumble last October. It was chamber of commerce weather every day! I was out there for the 4-day 2014 USPSA nationals where you shot 1/2 day for 4 days. It rained every day for about 4 hours. And those 4 hours lined up nicely with my squad's AM/PM/AM/PM schedule Hope for the best, plan for the worst

No problem. I hope you enjoy the match. It should be nice but don't forget foul weather gear. They didn't name it Hurricane just to be funny

Here are the rules and stages from the 2019 match. Yup, no power factor but expect to see large and small poppers, polish plate racks and spinners! I would not expect that 2022 will stray all that far from what you see here. 2019 Berry's Steel Open Combined Stages - revL 05APR2019 (modified).pdf BerrysSteelOpen2019Rulebook.pdf

last thread merged into the mutha waiting on Honchos thread...

Here is an archived thread on the subject. Unlike PCC, stroking is actually increasing the slide travel. I asked an open shooter about that with a comparison to why we short stroke a PCC. It seems counter intuitive from the PCC standpoint. He just said "it's better" than a non-stroked open gun.

Actually, they won't know. Contact the owners of the IRC

I hid a few ot posts from this thread. Please stay the course with the title subject.

Beven Grams has always said to use 11 for 140 and 13 for 170. If you need 13 to make your 140 work, there is something wrong with the tube. Cutting should work.
