I got a BCM SPR build in 556 & a Compass Lake .22 LR upper built like the BCM. I bought the CL 22 upper as a cheap way to practice on my SPR lower without spending a fortune on ammo, but I am questioning the merits of my decision. I mostly shoot at simulated distance targets at 25 yards designed to simulate targets at 50, 100, and 200 yds. But obviously the recoil and possibly the wind drift and drop are very different. Would I be better off selling the 22LR upper and just buying more 556 to practice with? Thanks.
