I recently acquired a TC 10" 22RF barrel with match chamber, took it to the range for its first function test with my "junk" bag of various RF ammo. I just grabbed a partial box of Federal Target "auto" in the white 525 size box, out first for a function test. That barrel actually shot this ammo pretty darn good IMO. Now, I'm new to the contender game, so take this for what it's worth, but at 25 yds (just stepped off the distance) and using 1" orange dots for targets on a cardboard box I pulled out of the dumpster from a wobbly bench on a couple makeshift bags, I was able to keep the majority of the shots in the 1" dot. I do have a 2-7x scope mounted on this and the TC forearm that doesn't ride a bag very well due to the slope. I shot the remainder of this box (50-75 rds) as I was so surprised at the accuracy this ammo, so now I have to find some more of it and hope it's as good. Also need to get a better forearm for it to see what it can do.
