I loaded some for a friend of mine that hunts with a tikka superlight using varget and I think I started off at 46.0 grains and went to 49.0 grains per barnes load data. There wasn't a huge difference in accuracy so we went with the 49.0 grain load to get the most velocity for expansion. He hasn't had a chance to try them out on a deer yet. I would like to try TAC with this bullet but I had a pound of varget on hand so that's why I chose it over TAC.
