Hello all, I’m new to the campfire. I’m trying to work up a load for a Portuguese Browning BAR in 30-06. I’m using 68 Lake City match brass, 150Gr Hornady 3031’s and IMR 4064. I have worked up in 1/2 grain increments to 47 grains. I don’t want to damage the rifle and I’m looking for advice on where to stop. Thank You in advance!
