Sparky,
What have you been feeding it, and how is it shooting? I'd like to hear how you're liking your rifle.
Probably a fair number of you are familiar with AR15dotcom. Within the contents of that site there are several reported KBs with Ultramax ammunition, which is remanufactured stuff. They (Ultramax) are paying for new guns for those who have had their rifle blow, so obviously there is a known problem, and they must feel like they are at fault. A few of these KBs have happened to members of that forum and they are posted in the first person, complete with photos. IMO it is pure luck that nobody has gotten hurt. Yet. Though I have heard of 1 report of injury-not in the first person however, so I don't consider it confirmed.
One of my rifles is a RRA tactical entry carbine, the same spec as the Bushnell Patrolman's carbine I believe. While using Wolf steel cased ammo I have twice had the rim of the steel shell break off the case, from the force put on it by the ejector, causing a FTE jam. The bolt cycled and tried to load another round in to the chamber with the stuck case in it. Both times I had to remove the shell with a cleaning rod through the muzzle. I only fired off a couple of hundred rounds of the Wolf, but those 2 problems were enough for me. Never again.
The rifle shoots better than my Bushy, which mostly sits around collecting dust these days.
Knock on wood, neither one of my rifles has ever malfunctioned at all using brass cased ammunition, including the 1000s of rounds I have loaded myself. I was just out with the RRA yesterday in fact.
Anyway, there are several known potential problems with steel cased ammunition, including what happened to me being 1 of them, and as I have seen for myself X2, they can cause an inoperable rifle condition-not a good situation if your AR is a HD gun like mine is. If your rifle has so far functioned perfectly fine with Wolf or other steel cased stuff, you're lucky, but remember that tomorrow might be your turn.
For a Mini 14 I'd shoot Wolf ammo all year long.
