Update: tested my loads listed previously. Functioned fine in both a Glock 19 (15 rounds) and a CZ P-09 (5 rounds). Didn’t shoot for group on paper, but seemed plenty accurate on steel plates at 15 and 25 yards. The bores didn’t show any unusual fouling, cleaned up fine afterwords. Will try again next outing. I like them, and the price is right! Thanks, Jake.
