I've been shooting CCI AR-Tactical* in my S&W 15-22 rifle & Beretta .22LR pistol to excellent effect; very accurate for .22LR.

TargetSportsUSA online and my local gun store frequently sell 300 round boxes for under $30, ~$.10/round, for copper plated 40 grain round nose, my preferred load. I save used 100 round plastic cases from CCI, Winchester, etc. and reload them 50 rounds at a time from the plastic inserts in the 300 round box. I find the plastic slide boxes easier to load from & less likely to get crushed in my ammo bag. Since the inserts are standard, they slide right in the plastic cases.

CCI Mini-Mags are equally good as the AR-Tactical but are a bit more scarce in my experience. Same price when in stock at TargetSports.

*Funny name: the ammo has little to do with Arma-Lite & is not particularly "tactical" IMO.
