    Was a little iffy about performance, seeing a couple of negative reviews. Performed fine. No issues, no jams, no problem. Great value. At the range I frequent, with range membership, I get about 50% off and comes out to about $325 per 1,000 rounds. I ordered 2,000 rounds of these and paid just under $500...realizing about $100 saving.
