Thinking of trying .25 cal totally new caliber to me, what kinds of groups are people getting with the standard liner and at which speed gives you the best accuracy, I've heard the slug liner shoots those better than the standard liner is this true?
+1 for Hekk187, all jsb 25s shoot good out of both, the mk1 Hvys shoot a little better than mk2 out of my slug liner, my A liner does seem to consistently shoot tighter at 100yds but the slug liner is one hole out to 50, then a little open after that. I run all the heavys around 880, hope that helps?
