I took it to the range this AM...
First off, when I bought this barrel it was not a good shooter. I added the DE-Resonator from Simms laboratories. Then it was a great shooter!!
Before this receiver I only had one sportster receiver. It shot on target with that receiver.
Enter the new receiver... It fit almost perfectly, well enough that all I would have done is a bit more engagement at the latch. But that's being picky, so I left it alone.
I was out of the SGB ammo I prefer to hunt with so I grabbed a couple boxes of R50, a box of Cyclone and a Box of Stingers.
It took me about 10 bullets to find where this hit at 50 yards!!! It was almost a foot high?!?!?!?! Remember it was sited in on the other receiver. NOT so with its new receiver!!! I adjusted and quickly found it still shot small groups back on target. Shooting fast easily on a nickel, settle down and do what your supposed to, and its at or under a dime.
The Remington Cyclones are part of a case I bought years ago because they shot so well from my Marlin Custom Squirrel. They shoot just as well in the H&R!! Again easily under a dime, just low centered on a 50 yard bull.
The Stingers are never great in my guns, but I like the performance on bigger small game. It shot nice groups just under a inch, I'll say you could almost always hit a nickel at 50 yards. Plenty accurate enough for the yardages the 22RF works at.
The Eley R50 is always great shooting fodder, that's why I always keep a couple bricks on the shelf!! (If you have never tried it and you have a good shooting 22. Buy a box and I'll bet the groups shrink!!) It shot nearly in the same hole the group gradually opened to less than a dime at the same 50 yards. BUT I needed to move the resonator. Before moving it it would shoot almost touching shots. I pulled it a half inch toward the forend and lo and behold I again found its sweet spot. I went back and shot the other two bullets and didn't notice any difference worth mentioning.
Temps where in the mid twenties, warm enough to shoot a while, but too cold to fiddle with cameras...
