My hunting buddy has some Xterminator I can try. I know his mini 14 target is getting 3300fps with the same loads I use but he put on an adjustable gas block and made several adjustments to reduce his brass ejection. My other buddies m&p Ar-15 with an 18" barrel was only hitting 2815fps with some loads he had done up, which suprised him as he thought they would be faster. I don't know what he was loading as we were all shooting over the chrony with the loads we had done up.
