Subsonic .22's

Ruger kmk10 and Aguila SSS.............WAY COOOOL!

Not suppressed, but not loud. Accurate and they function flawlessly. these CORN, PLUM, GRAPE, PEAR, STRAWBERRY AND TOMATO STEALING SQUIRRELS are in trouble now!

I know this is an old thread but I just saw it and can't help thinking the twist rate is too slow for those rds. Are you saying they group nice & tight without any tumbling?
I've never tried the SSS rds but then again my MKII Gov shoots great with a can and Aguila subsonics.

I have not seen much accuracy out of any of my 22's with the SSS.
However it does much better out of my AR with the 22 conversion installed, I suspect the 60 gr is more suited to the faster twist.

Ok, took me almost a year to find time to wring 'em out formally, but here it is: Ruger KMK10 AT 100 YDS

5.5 TO 6 inch groups with Aguila Super Sniper Subsonics
2.5 TO 3 INCH GROUPS WITH AGUILA SUPER EXTRA
SSS showed evidence of keyholing, but, with that performance WHO CARES!

So to answer, the above posts, yes, it does keyhole, but that is accuracy I can live with!
