I successfully loaded 300 rounds of 308, doing the load development thing, varying powder then varying OAL to get a round that shot at less than 1 MOA. So I am tackling 223. First problem I run into is it takes quite a bit of force to seat the bullet. The bullet is so tight it wont come out with my inertia bullet puller. I can pull one out with vice grips and pliers (ruins bullet, case ok, but scratched), but JUST BARELY. Whatever neck tension I have seems to be pretty consistent. I was used to a lot less tension with my 308's. Just enough to keep the bullet from moving while being chambered in my bolt gun. Do I have a problem or am I ok here? (Ive only loaded 10 rounds so far and am about to load up 50 or so more). Wanna kill these ads? We can help!
