Have to shoot yet. The RD 265 at .433" was hard to chamber but sized at .431" they fit good. I was sure I had a .432" but not. I swore I had all sizes. We will shoot tomorrow with AA2230, 5744 and 4198. Just below max loads.
My friend has factory loads and the bullets are all different.
I hope the RD will shoot.
OOPs, it is a .444. I can't change the heading.
