[QUOTE="backwoods83, post: 866661, member: 29890"] Yes you can gain or lose velocity by switching nothing but bullets. I have went from 140amaxs to 140 Bergers, both seated to the lands and had to add .6grns to the Berger load to match the velocity, doesn't bother me though, either shoots under 1/4moa. In the OPs case the NBT is longer, has a longer bearing surface and a thicker jacket than the Berger, these all aid in adding extra pressure or in turn extra velocity. Btw 32xxfps with a 168 is very tame, that's on 24" barrel 300wm level. The Bergers or Noslers will both safely go over 3400 with H4831 or Imr7828. [/QUOTE]
