The XPert bulk stuff is spotty. I have a couple bolt rifles and revolvers that shoot it REALLY well. Some of my semiautos shoot it okay, others not so much. The last batch of it I bought had oversized bullets that gave me chambering problems that could have been downright dangerous in some guns. From now on I'll only shoot it in my few guns that REALLY like it, and I have a good supply on hand for that purpose. Prolly won't be buying any more of it for a LONG time.
Now, their Dynapoints, if you can find them, are fabulous. VERY accurate, very reliable, work in almost everything. Sadly, they now cost much more than other bulk ammos. If they were the same price as Fed Bulks and Rem GBs, and I could get all of them I wanted (which I've never been able to do in my area), I would probably never buy any other kind of ammo.
