Bullet weight for 1:8 260 remington

[zloe]

Same 120's-up to 147's, but freebore is the deciding factor. My preference is for 140's as I feel it's the best balance between BC, velocity, and barrel life. My last chamber however, was cut with a reamer designed for 130's and 140's sat way back in the case.

So take measurements and pick the weight class that best fits your chamber then tune it up.

Thanks.
Perhaps my gun is an anomaly, but I may have had better accuracy throwing rocks than I did with the 120s. I'm just glad it was a box of factory ammo and now I know.
