| I was wondering do you have to trim new .223 cases down to the required length? Or can you just prime, powder, and seat the bullet? |
| I just load new brass as is. Been doing that for .223 and .308 brass. Try them in your case gauge. They come from factory to correct spec. Only reason I could think of FL sizing is when you have load custom match rounds. Just using new winchester brass from midway, shooting sub-moa is not too difficult. Just prime them, charge powder. Seat the bullet and ready to go. I always keep few hundreds of new brass Jjust incase I fall behind processing old brass and need few hundred the next day. You will discover that with reloading, large amount of time is spent on processing brass. If you FL size new brass for ARs, you are over working new brass for no reason. IMHO. |
| I think I reloaded brand new rifle brass just once in my life. It was IMI 762x39 cases, I just full length sized them, they didn't need trimming after that. It didn't over work the brass since the cases were already sized. The benefit came from deburring the case mouth via the expander ball and removing existing case mouth dings. I think one flash hole was declogged during the process as well |

New brass just means it has never been fired. Not that it is ready to load accurate ammo. Necks will have dings, may not be round, and the cases will not have concentric neck length. They will look like they were trimmed crooked, with burrs. The case length will be all over the place also. If you just want to make noise with your ammo and blast away, then go ahead and load them, and be happy with the  But if you want accurate ammo, case prep is necessary. Full length sizing, delube, trim and debur, check in case gauge, then load. If you are crimping your loads, case length should be uniform. |
