Let me say first that I read as far back as I could access hoping I wouldn't be repeating a dumb question. Here's my situation before I ask the question. I'm not one of our heroes in uniform, I'm a 53y/o civilian that likes to shoot and likes to be prepared. I just replaced my trusty Stag carbine (1:9 twist) with a Bravo Company middy with a 1:7 twist. That's something brand new to me which is why I'm bugging you fine folks. I like to keep a good bit of ammo around for a rainy day and to stay in practice and have 1500 or so rounds of Lake City XM193 plus some mutt stuff.

I'd like to add another 1000rds for a rainy day plus the same in practice ammo. As much as I'd like to have 1000rds of LE grade ammo put away I can't afford it. So my question is should I stay with XM193 or move my future purchases to the pricer XM855. I want to standardize on something so that my rainy day rounds are the same as my practice rounds. Thanks in advance!
