Yeah, the stuff I tried is the Hornady +v 30 grain designed for varmint hunting with a rifle. The new CD ammo uses a 45 grain bullet. That 30 grain stuff wouldn't even hit paper at 25 when it did go bang, either, way off POA. If it misfired, happened every cylinder with at least one, it'd always bang on the next hammer fall, so the ammo just seems to have tough rims.
As to .22 not going bang, I change my ammo, especially in summer, every week. In a hot, sweaty pocket, the stuff will go dud on you after a month or so in my experience. I get always bangs in the little NAA by doing this, very low risk of a click when the trigger is pulled. But, yeah, rimfire is susceptible to moisture in a sweaty pocket. I just take these rounds that I've rotated out of the mini and fire 'em off at the range.
The magnum gun, I rotate the rounds out about every 3 months since I only carry it on Sundays and every now and then for a special occasion. I sorta trust it more, but haven't proven that it's more moisture resistant than the .22LR's heal seated bullets, yet. I suspect it is more resistant, but I wanna prove that before I believe it.
Anyway, heck, I rotate out (or actually SHOOT) my centerfire carry ammo more often than that.
