They are the best long range bullet I have ever shot in a muzzleloader for accuracy they seem to match up with the 1-28 twist in my Omega and Triumph better than any thing else,the I-38 twist in my System One wont stabilize them. I have found several loads that work well with them, in the Omega 90 and 150 RSshoot very good groups at 100yds 100gr of RS shoots almost as good. In the Triumph they shoot well with 90 100 110 &120 gr 777-FF but 110 seems a little more consistant; I am only using a 4 power scope and thats what I like for hunting [1.5 X4x32] when I put a good 7power or more I can tell some differance but unless I boble it I usually dont go over a 1.25 inch group shooting two shots before wiping. [ practice for hunting] When I put the good scope on and clean every shot I can get dow to .75 sometimes. Lee
