Poll: What weight bullet?

[photoracer]

I am mainly shooting 140-150 PF factory 147g loads out of my Open G34 (it likes Fed AE or Fiochi 147 ammo best). I have 161 PF NATO 124g loads but I realized I needed a stronger spring after shooting them once. Now I have a pair of 20/22 lbs. springs to experiment with. In my STI I usually shoot a 124g Ranier plated behind 8.xg of AC with a shorter OAL to give me 177 PF in 9x23mm. Gun won't cycle consistently if I try to down load it to below 160 PF for steel w/9# spring and reduced loads of AC or HS-6.
