Just a little confused on 45 colt here. I'm thinking of picking up a Henry rifle in 45 colt and looking at my reloading manual it has different recipes for older guns and newer revolvers but how can I be sure exactly what the limits are for a new rifle? I've never loaded for this before (or anything coming from black powder really) but I like the idea of something a little milder for range plinking but that I could punch up a bit if needed. Just sort of wondering where to start it seems a bit silly to start really low on a modern rifle but at the same time I'm a little worried about starting a bit too hot and wrecking a $1000 gun and/or my face.
