Replaced the breach “O” for my new .25cal RE-Q. The thing was shooting lights out first 2 trips. 3-4 trips accuracy was HORRID! Apparently, I pushed out rear “O” ring.
Everything is now shooting great again. Now for the weirdness.
1. WITHOUT breach “O” ring it will shoot 31gr slugs great. With “O” ring accuracy is a complete fail and is shooting 3” higher. With about a 3” group.
2. This barrel really favors 33.95gr pellets. They pretty much stack in the same hole when I do my job. The next best pellet is 20gr. Everything in between is not head shot accurate for coons.
3. The 20gr pellets have a “ping” noise when leaving the barrel. I’ve isolated sound to a). The thin skirt being released from the barrel. b). Maybe I shouldn’t be using that light of a pellet. If you have an idea let me know.
4). What’s up with the diameter difference with all these pellets? The least accurate are the JSB’s Hades .262 diameter. But the most accurate were JSB Heavies and Hawki Thunder both being .259 diameter. Grizzly slugs were .250. Vortex Strikes .253 and H&N Field/ Trophy .257. It seems to me a little more consistency in barrel ride would help with accuracy considering my most accurate were right at .257-.259”
