I hunt with a .260 Remington and have primarily fired factory 120 gr Federal NBT's with great accuracy and consistency. It was no different today as I took a half dozen shots from 100 yds and maintained a super tight group through all 6. After this set, I tried a 3 shot series of 140 gr Remington BTSP's out of shear curiosity, and although they too maintained a sub-MOA group, that group was nearly 4.5" lower than the group shot with the NBT's. I maintained the proper time between groups to ensure i didn't overheat the action or barrel as I switched back and forth between the two different cartridges. And the results were identical through it all. I know that different bullets perform differently, but have never seen a 4+" difference between cartridges at 100 yds with this kind of consistency. Can any of our smart rifle/cartridge folks help explain this one to me? The rifle is a Savage 110 with 22" barrel, all factory, and a Nikon 4-12×40 BDC Scope if it matters. I'm open to any ideas as i research this more.
