I've had random success with CCI SV. One group will look good and then the next group will have a flyer or two. It's made me stop trusting it.I sent Yo Dave an email. Maybe get an explanation why there is an extra 10 bucks dded to the price.
On a different note, I backed my action screws down to 20 inch pounds and accuracy improved. The rifle shot really well with SK standard, not so well with CCI SV. I was hoping it might be the other way around as I have two bricks of the CCI. But my T1X shoots the CCI pretty good IIRC.
