Just put together a ctr with the 20” barrel, going to use this in midrange ftr hopefully. Shooting 175smk great, with imr 4064. It likes light loads at 39.3gr, anything over 39.5 and the groups are over half an inch. But the velocity of the accuracy load is only 2275fps, and goes transonic around 950. And ideas on how to get more velocity out of it without a lighter bullet? Think it might like varget at a higher charge?
