I usually shoot piston ARs, so I turn the gas completely off tot he piston system and avoid lead deposits into the gas system/impingement tube. I just recently built an impingement gun with a 16” barrel but mid-length gas tube. I’ll be shooting a lot of .22lr through it using the CMMG kit. I don’t intend to shoot the 60 grain subs through it since the impingement tube might be fouled from heavy lead at low pressures (compared to the 5.56 rounds it will also shoot).

I’m going to test the rounds in a variety of .22 tools, like the SR22, the 1022, and a couple of revolvers and a lever Henry youth model. I’m curious, and the ammo is available because most folks have not been introduced to it.

I have not fired the round being discussed through the 1022 but it is my understanding that the twist
will make the round lob or tumble due to the weight.of the lead. I'll check the stats on the barrel when I have time.

The sub sonic SSS likes the 1/9 twist of the AR. The .223 5.56 can handle that because of velocity. vs twist.
and copper jacket. Let me know how it goes from 10-50 yards in a stock .22.
