AMMO RECOMMENDATION: For in-house testing, we utilize CCI .22LR Mini-Mag 36 Grain Copper-Plated Hollow Point Varmint Ammo (1,260 FPS). We highly recommend this ammunition for use with all RTB .22 barrels. It is important to note that the use of underpowered or economy-grade ammunition may lead to less-than-optimal performance outcomes.
