I just picked up a 340 in .223 that looks like it has had very little use. After doing some reading I know that it has a 14-1 twist barrel.
Has anyone any input on suitable factory loads? I have some PMC 55g (not great I know, but they were cheap). Would these stabilize or do I need something lighter?
I do intend to load for this, but want to get some usable factory ammo initially.
