I haven't gone the 3-sies but have several 5R's...
So, upshot is you're going to have a dedicated set of brass for this one, eh?
The more I think about it there is a heck of a lot more stress on the lead forced against the edges of the grooves.
The JP gets Lapua brass so this one gets most of the Hornady brass from my old 18" barrel. I used a little of it to get the 243 going and then just ordered 500 virgin Hornady from Graf's for that one at 35ยข per. So at least I can keep it long for the pistol.
Let's go Brandon!
