7 1/2 shot at 40+ yards... Hevi-shot may, may get some penetration at those yardages but I'd have to see it to believe it.. I shot some 7 1/2's, Federal 2 oz a few years back at a little cardboard device I made..it had 7 sheets of cardboard inside, compared to the big 3, 4-5-6's, they did not do well, only two or three sheets compared to 5-6-7 sheets for the others. I''ve never tested Hevi-shot 7 1/2, they would do better in my opinion.. Any one ever skinned out a skull shot at over 40+ yards..did they make it throught the skull plate?? 45-50 would really be a push compared to 5's and 4's.... Some of you may remember ACTIV...shells, they bounced off and had very little penetration at 40+ yards... What's the cost of the NITRO shells ??
