The Lancaster that had arrived needing a new butt pad is now ready to try out. It's in 500/450 3.25". My plan is to take 500/416 brass and see if I can neck that up in my 500/450 2.75" dies. If not, then I was going to try fireforming with cream of wheat or grits, but that takes a 45 min drive each way to where I can shoot. Hopefully necking up with dies will work.

Any advice on either approach?
