Previously, I fired several hundred rounds of Remington bulk packed Thunderbolt and fifty rounds of CCI Mini Mags, which both functioned flawlessly, although the Thunderbolts leaded the bore grooves (which was, however, easy enough to clear out during normal cleaning).

Yesterday, I fired about 275 rounds of the Federal Value Pack .22 Long Rifle, and had three or four failures to eject the spent case, requiring that I rack out the spent case and chamber a live one from magazine manually. Otherwise, function was flawless, and no leading of the bore is observed.

For truly flawless function, it looks like the Glock needs the hotter stuff, but for practice shooting there's no reason, IMO, to disdain the Federal Value Pack ammo. Three or four times, out of 275 rounds, having to rack the slide to get her going again is no big deal on the range. If I were using the 44 in a match, afield, or for self-defense, I'd keep it loaded with CCI Mini Mags, however.
