The 60-grain Aguila subsonics burn filthier than anything I've ever shot except black powder. The carbon residue causes jams in the rotary magazine inside of 20 rounds. The smaller a charge is, the more even the smallest variations affect MV and the Aguila SSS's charge is so tiny and their QC so slipshod that (chronographed) extreme spread in the brick I bought is more than 10% of the average MV. And such substantial variations in MV guarantees vertical stringing. I bought a custom 1:9 barrel to use the SSS 60s in and it struggles to shoot 2-inch 5-shot groups at 25 yards. With any other ammunition it shoots bugholes, so it's not the barrel. The 60-gr Aguila ammunition is crap.

That has not been my experience using the 60gr Aguila. Sure it shoots dirty, so what? I have not jammed my rotary mags after shooting 100s of rounds of 60gr. You are only getting 2+” groups at 25 yards? I shoot 5 shot groups and get many cloverleafs, 4/5 shots under 1”, and maybe a flyer to open it up to 1.5”. For what it is, it works for me.

Most of the time I shoot Federal 22 Auto Match 40gr, and it’s slightly more accurate and consistent. (I buy both in bulk)

But the 60 grain subsonic is meant to be quiet and hit hard. I can ring 18” steel targets at 200 yards all day once the range/holdover is worked out. It really takes a while to get out there, Pow.......ding. That’s good enough for me.

Appreciate you guys' insight on this stuff. I've spent a few hours over the last couple of days lookin' in to droppin' the coin on the barrel / ammo / stock. While flingin' the heavy chunks quietly is appealing, 1-1/2" / 2" groups is not.

My reading has led me to the conclusion that the tight chamber in the aftermarket target barrels has as much or more to do with 10-22 accurracy as any other single factor (besides ammo). Green Mountain offers a drop in 16.5" with the tight ("Bentz") chamber. Perhaps that'll get me the sub 1" groups I'm after witout goin' full blown heavy bull / stock combo.
