I think for bowling pins a 165 grain bullet going 1100 fps will not have a high enough power factor. For pins IMHO you need at least a 215 PF - your load will be about 182. To get 215 you will need a velocity of about 1300fps - higher than recommended by the mfg.

I always use 200 grain Hornady XTPs going at 1100 fps using AA 9. It will sweep the pins right off the table.
