Reloader 22 is a way slow powder for the round. I have had good luck with H-335, Varget, and IMR 4320. With the 4320 working best across tie board in all of my Mosin Nagant rifles. For super light 110 grain bullets H-335 makes a great screamer load, that has a huge muzzle flash. I get a hoot out of lighting a few of them off every once in a while. For the most part I use Speer Hot Cor 150 grain (.311 diameter.) They give me exelent groups.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
