I have a lee setup for 44 mag I have used it to load some pretty good loads for a 4" Taurus I have. I recently bought a Ruger "old" vaquero and am trying to loose a raging bull for a redhawk. I bought a Lyman 45 lube sizer in order to eliminate some of the lube mess and to be able to size my boolits a little better and seat gas checks. Can anyone help to explain how and why you slug a barrel. I'm looking to get the most out of a pistol as I can. I hope to hunt with the 4" Taurus and the Redhawk but I enjoy small groups maybe even more. The Lyman will take all of the Lyman and Rcbs dies correct? I keep reading about a O ring but the Lyman 45 will not be here for a week or 2 and I'm trying to get my ducks in a row. Also a top punch for a 480 ruger I see some Rcbs dies but no top punches. Any and all help is appreciated and I wish you all a Merry stress free Christmas.
