Lee - Wow, are you saying that you've used 175 grs of powder in a 58 cal load? I came up with this figure using the following: 5/8 * 280 gr (approx weight of 58 cal RB) = 175 grs. If so, that is one hell of a load!![8D]

Geez, I never heard of a 1:80 or 1:100 twist. Does anyone today make a ML with that slow of a twist?
