Re: FACTORY PRIMED REMINGTON BRASS????
Yes. Pro- You don't have to buy primers and seat them. Most are ready to load, with a little cleaning up of the necks.
Con- you can not control what primer they put in. Once you find a load your rifle likes, do you know what primer they put in there so you can duplicate it. You're limited on the case prep you can do since there is a primer there (can't tumble or size with lube). If it's plinking ammo, then this may not apply.
