Yeah. I’m kinda wondering if they are just snake oil. I’m gonna try a shaft collar on my barrel, moving it a couple thousandths between groups before I drop $200+ on a tuner unless I come by one for cheap.
I’ve been reading up on Tuners for 22LR. Do you think it’s a must have for a rimfire that’s used for PRS22 matches? I like to use CCI standard velocity because I have a stockpile of it and it doesn’t group the best out of my rifles, I’m hoping a tuner will help.
