The Harvestor is OK on smaller calibers but not as effective on .223 as a dedicated .223 cal can. Son cracked off 2-3 rounds to check zero on a 16" AR w/Harvestor yesterday. I was working 50 yards behind the shooting bench and the sound was comparable to shutting a vehicle door 20' away. More of a muffled whump than a muzzle blast. The downside is length.
The Sparrow is a good 22 can with only moderate FRP and handles HV ammo quite well and sub-sonic extremely well. Not as effective with 17 HMR as a bigger can but not bad.
