Re: Which custom build would you go with?
It is a light backpacker 1000 yard rifle and no more so the best performance is with the lighter bullet. If you think you will shoot beyond 1200 yards the 252 grain cutting edge at .72 bc or the new 260 grain at .76 bc would be better. The 252 shoots around 3100 fps out of the 26" and I have not tried the 260's.
Predictions are difficult, especially when they involve the future
