Simple as that... I was using some cheapo blazers for the first 100 rounds, but don't want to risk any unnecessary damage to the gun by continuing to do so, if it weren't recommended. I didn't see anything in the user guide as far as brands to stay away from or preferred, but that doesn't mean users haven't found something that Ruger can't list without certain liabilities... And i'm just talking plinking and practice ammo, of course. So keep cost in mind. I'm not asking for gold plated our anything... Haha Thanks.
