The sweet spot I found for my cast bullet loads for my 45 Colt was right at 1,150 with a 320 grain LBT style with a very wide meplat cast out of wheel weights and quenched in water. Out of my 7-1/2? Blackhawk they create 6 shot groups at 25 yards that touch when I do my part. I?ve always gotten straight line penetration with them and have had no problem sending them through both shoulders on hogs and they make nice round 45 cal holes going in and coming out. I have not been able to recover any to determine if the bullet is deforming much, but at those speeds and looking at the evidence during the autopsy I don?t think I am having any significant deformation. I wouldn?t be afraid to send them through an elk at that speed, but would need further testing before I sent them through anything large and nasty that could do me harm.
