Just wondering if it's advisable to use this for let's say a 230gn 45Colt load going around 950fps. I've around 40lbs that I was originally setting aside for 7/8oz 12ga slugs which gives me in the neighborhood of some 730 odd slugs. I'd be happy with about half that as I don't see myself shooting more than a dozen per range trip where I bring along the 12ga. Any advice is much appreciated.
