Got a .30 cal rifle barrel with 1:10 twist that I've been trying to shoot 130 grain pills out of without much good happening. Today, shot some 155 grain with pretty good results. Am now thinking that 1:10 will not properly stabilize the lighter pills. Do not really want to go heavier than 150's if I can help it. Wondering if 150 round nose would have a longer bearing surface and thereby have better stabilization in the 1:10. Also thinking that I need something with a 1:14 to stabilize the 130's............................... Thoughts???? Thanks.
