I am talking about .223 bolt action rifle here.
Ok, I am almost ready to start resizing. I have some once fired brass from factory ammo that I will experiment with between the three types of sizing. Once I have it all figured out, then I’ll start using some new Winchester brass I bought.
For the new brass, do I need to FL or partial FL size it before first use? If partial FL, how much do you back off the die to partial FL? Down the road after I have neck sized only for a few times and I need to “bump” the shoulder back, is that the same as partial FL sizing?
Thanks.
