colt 45 mares leg

I've been loading 270 cast SWC gc with 2400 as hinted at by Dave Scoville and Brian Pierce both at one time or another. It seems pretty snappy and the shells aren't sticking in the chambers. I have also been using a 260 grain cast with a smidge more 2400 in a '73 Win. replica. I think the 73 load is around 16 or 17 thousand CUPs, a little hotter than saami specs., and the 73 doesn't have that strong of an action.
