Model 929 from the Preformance Centre

Ok gentlemen, I use my gun for Competition IPSC, few things I have found..
1) only use brass fires from new in the 929, Starline is my choice,
2) Moonclips .025" thick
3) 147Gr Projectile
4) ADI Powder AP70 ( Slow Burn) 2.9-3.1 gr any more & they expand the case to much & stick in the Cylinder
5) Federal Primers & adjust the Main Spring back to suit.

This setup works well, the Cylinder doesn't have a special coating in it, it is just titanium. The 929 is a fantastic gun & needs a special diet for reliable competition use.

The moon clips I use are from TK Custom or Revolver Supply and are .040 or .035 inch in thickness. I don't think .025 thick moon clips will work with 9mm. They work great for .38 Special in my 627 and R8.

My bad guys
...I found that one of the casings was bulged at the bottom...

There are bottom feeders when shooting stiffly loaded rounds will bulge the web, or bottom area of a case. Not mentioning any brands or loads, but if you collect range brass you will surely have some.

The bulge is too far down for the sizing die to reach. In .40s&w there are push-through dies that can correct this problem, but since 9mm is tapered there's no solution.

About the only way to avoid it is to re-size your brass then run them through a chamber checker. It's an extra step but well worth it.

There is a fix, Lee 90807 Carbide Factory Crimp Die 9MM Makarov, just remove the internals & push the whole case through die. Brings them back to New.
