I am going for lower PF loads so want to stick at or just over 1050 to make the 130PF which I will use for USPSA and IDPA both. No sense in having 2 different loads.
I am going to drop down in 0.010" increments and see what I get. Worst case, I just use the 1.158" I am now, and deal with it. Definitely not a "deal-breaker"
Read my blog on vel/pressures vs OAL. Reducing the OAL will increase your vel or you can leave the OAL alone & up the charge a bit or you could try a mag primer. Either way, you are going over 1050fps. Really, it's a 9mm, I doubt adding 50fps changes the recoil impulse all that much.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
