This may be the wrong forem ..... having 2nd to last shot jam, nose up, in UZI mag from RRA. The load was 7.8 gr of AA#7 w/125 gr Rem bullet/small pistol primer, assorted cases. Also occurred using NORINCO 9mm ammo. Mag loaded to 25 rounds.

A suggestion was to load "hotter" and graphite the mag. SO I am loading 8.3 gr of AA#7. AND will graphite the mag...............

Thoughts??

thats sounds good i shoot 8.8grs with 124 raniers. havent chronoed them yet. but figure i get 1225+ out of my beretta. loaded COL is 1.16" a pretty accurate loading form my gun anyway

If you are getting jams on your next to the last round with two different make bullets, it is probably the spring tension on the magazine not the rounds themselves. Try AA#5 in the 9mm if you haven't. Kudude

Thanks for the input. The 8.3 grs of AA #7 has a OAL of 1.132 and the 7.8 gr loads were 1.120
I'll work the mags.
