[QUOTE="Fiftydriver, post: 1721620, member: 10"] This rifle has a 10 twist so very limited in what bullets could be used. This was a rather rushed test rifle assembly i admit!! Production rifles will likely have 7 twist barrels to use the 128 gr hammer hunter bullets. BC drop off at longer ranges is relatively common when using a solid bullet design in smaller caliber. Just not enough mass, momentum or inertia to maintain BC. A lead core bullet design does much better at maintaining BC at long range but solids have benefits over lead core as well, especially at 4000 fps plus muzzle velocities. I do not believe there is any melting off of the tip. [/QUOTE]
