The SBK 39 gr shot the best for me. Mind you, I started out with Hornady 40 VMAX and Sierra 39 BK, only. Never have tried any 32 and only once, the 26gr Barnes. I have tried Berge 35 and the shot ok and would probably do well if I put the effort into them. But (IMO) the 39 SBK will do anything the 35 Berger will do for just a tad cheaper.
Did it shoot well before cutting the barrel? If so, it sounds like the crown may be at fault, or you changed the harmonics enough to dictate new load development is in order.
The 39's shot great. .25 at a hundred. I am not for sure on the speed yet. I do not have a crono. The only way i can get my speed is by figureing the drop.
