You Know the inkering you get when you accumulate a bunch of reloading stuff for a rifle or pistol you do not have? Well, 9 MM brass grows on trees around here. Came across a die set and 1000 bullets with it.
I shoot a 44 mag and a 45 acp. I am pretty good with both.
Aside from the excuse: Why Not, or: because you don't have one, What good is it? What does it do any better than my 45? DO I REALLY NEED ONE?
Aside from casting my own boolits, which I do for the 44 and 45, there is no money savings whatsoever compared to buying store bought factory ammo.
