Well, I did a little fiddling with my 22LR handi over the weekend. Trying some other methods to float the for-end to tighten groups. First I cleaned the latch and barrel shelf. Then I shimmed the barrel stud with a dead flat steel washer and attached the for-end. Lastly I affixed one of the shooting de resonators and slid it down 2 1/2" off the for-end.
At the range, I set a target at 50' and started shooting. I shot five fouling shots then shoot 5 rounds for group. All following pics where shot form same gun, with same ammo, (Remington Cyclone 22LR.) at the same distance, off the same rest. ONLY change was to move the barrel de-resonator for each group. Distances are away from the for-end.
Here is the first group. Before any adjustments;
I added the De-resonator 2 1/2" from for-end and shot this:
Pulled it in 1 1/2":
Finally pulled it to just about 1";
All I can say is WOW, I put little faith in this rubber thingy. I am a believer now!!! Guess another order to Midway is in order...
