Ray, i have hesitated getting into this one because I honestly do know the twist rate of the GM-LRH 45 cal barrel. I have a couple of 50 GM's and they are 1/28 and I would assume the 45 would be the same thing.... BUT.... GM seems to believe that 1/30 twist (mathematically) is the ideal twist for a 45 and the shorter 45 cal bullets available. So when you look at a .451/488 gr. Bull Shop how that might do in that twist - I am really not sure. If the bullet is made well it should be OK but I just do not know.
