i got a cz97b recently and had a lot of problems the first range outing. i had a lot of failures to go into battery and as per input from the members of THR the most likely cause was the bullet being jammed into the lands. The problem was with my 230 gr hytek coated MBC. the coal was 1.270. ( works well in my sig p220and 2 191s)
I compared the plunk test of WWB 230 FMJ in the 97b barrel compared to my reloads. The WWB dropped in and fell out easily. i tried 1.260 but it didnt drop out as easily till i used about 1.250 -1.253.
i shot 100 rds of WWB and close to about 60 to 70 rds of my reloads at 1.250. No problems with feeding and all went to battery. the reloads at 1.250 performed pretty much the same as the 1.270s. I also compared the performance of the 1.250 vs 1.270 in my 1911 and didn't notice a difference. so I'll reload at 1.250 next session. Thanks for the advice!!!
i noticed the gun was slighlty shooting to the right the first time so i drifted the rear sight a bit before the trip and fixed he windage issue. Inserting a full mag is still not smooth and sometimes gets hung up . Will see how that goes.
1st pic 20 rds per target WWB 10 yrds offhand
2nd pic my reloads same distance
3rd pic 25 yrds. there were 6 rounds that didn't make it onto the black. offhand except for one magazine rested.
