Bullets came in the mail yesterday...super fast and deserving of a shout out to https://www.bluecollarreloading.com in NC. First time I ordered from them, or even heard of them. Prices are low end of the spectrum, and shipping was flat rate. Downside is they don't ship powder/primers.
She feeds beautiful and smooth with the 220 RN. 35.5gr of IMR4064 should get me somewhere between 1900-2000FPS. My Lyman manual says this is well below max. My Hornady manual starts at 29.3 @ 1600 FPS. I'll start there and work up to 35.5 and see what happens.
Thanks, butlesrangers. I'll be measuring the tenon to make sure it has the right one. The seller sent the CMPicon certificate with it, and said it was a VFW turn in. CMP's website says these are all mixed-masters so there is a chance it has the wrong side plate on it.
