Have an old long action 110 Savage. Going to build a 7 1/2 ish # rifle 22” barrel. 7mm08, 280 or 284 Winchester? I like the option of Lapua brass in the 08 but it’s the slowest of the three. Peterson does make 280 brass and it’s the fastest of the three. The 284’s accuracy and ability to seat out long in a long action is a plus. What ya’ll say.
