I picked up a bunch of these that weigh 229gr, and are sized .309. I load for 30-06 in a 1903 Rock Island Springfield, a Remington 700 Varminter in .308, and 30WCF in Winchester 54. Some powders I have on hand are 4895, 4064, 3031, 4350 in IMR, Unique, 700X, Varget, and some others. I want to shoot these at 100 yards in local matches. Ideas, comments, and opinions wanted! Thanks in advance!
