Fireforming Norma Brass for paper patch loads

[Opencountry]

Hello gentlemen...and ladies, if there are any,

I just fireformed some Norma brass intended for pp shooting. Before stuffing the cases with my usual pp load I FL-sized the cases and trimmed them to 2.885" for my 45 2 7/8" chambered Shiloh. I use a Meacham neck sizing die to size about .10" at the end of the mouth of the case to seat the patched bullet. When stuffing the wads on top of the compressed powder column they fit the FL-sized case tightly, so tightly they actually buckled. This left my loaded round OAL's inconsistant with one another. I usually size just the mouth of the case after the cases are fireformed, the wads sitting atop the compressed powder column nice and flat. Well, I wasn't expecting very good results, just wanted to fireform the new Norma cases. I was surprised at the results. Here are two 200-yard targets. The one at the top is using a rear bag for support, and the target at the bottom I'm using just my shoulder for support. After firing the cases they measured 2.880" in length, just what I was shooting for.

Edit: BTW, the chamber measures 2.878".
