I am in the middle of building a mixed use, primarily hunting rifle for WT deer we can hunt with a .223 in Georgia. I reload and the choice is a Noveske 18 inch LW Mod 0 barrel to cast the 62 grain TSX at about 3000 FPS or their 18 inch SPR 6.8 barrel with 1-12 twist to shoot the 110TSX at about 2700 FPS. The BC of the bullets .287 for the 223 and .323 for the .277 are enough different that there is only 1 inch of drop distance at 300 yards which is as far as I feel comfortable shooting at a living animal. It is a tough decision as the 6.8 is the most logical from a pure killing perspective, yet the special bolt, magazine, AR's that fling costly brass into the next county, availability of cheap mil surplus .223 ammunition requirement for two upper if you want both choices make this a difficult choice.
The best "THEORETICAL" answer that I have seen is that quick barrel change nut by M & A parts. Buy one upper, one scope, two barrels, two bolts. So far I know nothing about this but am going to speak to Noveske about it.
all that said there is not a deer in GA that will not die when hit in the front half by a 62 grain TSX! Please don't tell me anything about what kills and what does not as I am one of the so called "Fudds" with 42 years of hunting and shooting experience and have seen animals run up to 100 yards when hit squarely in the chest/heart/lung with anything up to a .308/180 at 3000 FPS. It all "just depends".
