Ok not really sure where to put this just it is several questions. Let me give a bit of background. I have a ruger sp101 in 357. I have castes for it and I am now looking to go to a rifle. It looks like after much consideration I will be going with a Henry big boy in 357. I was looking in my Lyman 48 and found that there is three different sets of loading for the gun. I want to run a 38 casings with a 358429 170 grain cast. I was going to use Felix lube and for running the bullets in the revolve was not an issue, but I looked up the fps for the rifle and it was getting up there like 1700. So I guess the question is will only running 38 casing make that big of a difference in the rifle. I want to be able to run the same load for both the revolver and the rifle. Please any thoughts on this would be great
