Is their a difference in Ammo brands such as one would dirty up your rifle faster than a cleaner burning brand.
This is what I have, and if one burns dirtier that the other when used up I will not buy that brand any more. This is for the 223 caliber.
In my experience, Federal ammo is dirty and Blazer ammo is filthy. I shoot Remington every now and then and I seems to run a LITTLE cleaner than Federal, but is not worth the extra price in my opinion.
I always buy dirty ammo for plinking, because I get cheaper stuff and cheaper usually means dirty.I've never had one malfuntion with Federal, I've had about 6 with Remington. (Not UMC though)
