Anyone have a clue why the SPR 22" barrel version is 1:8 twist, the standard 26" barrel is 1:10 twist, but the 26" long range model is 1:8 twist again? I get faster twist rate for heavier bullets and heavier bullets have higher BC, but why would the short barrel "suppressor ready" version be a faster twist?
From what I read, heavier grains lose FPS more from shorter barrels. You'd think the 22" models should be lower twist rate to encourage lighter bullet use.
