I have a BT22LR black pistols and I have and have used the following over the last few years in it.I need Simone that has one of these guns let me know how it works with cheep ammo or is it good stuff only.
we only get ammo once in a blue moon mostly Remington gollden, thunderbolt we get CCI standard as good ammo CCi Min Mag is hard to get
Blazer - 40 gr
CCI mini Mag - 36gr
CCI Stinger - 36gr
CCI Volocitor - 36gr
Remington Yellow Jacket HP - 33gr
Winchester - 36gr
I have had some misfires however not enough to require self repair or real gun smithing repairs. I use my BT22 more often now since the price 380 ammo is still higher than I would like and i only shoot for enjoyment. My 380 and 357 are used for SD.
P.S. the 22LR ammo I have and use are from the Dark Ages when the manufacturers took their time making their ammo and not running their equipment 24 hours 7 days a week to keep up with the demand.
