Hi All
I am a rimfire bench rester and went through the pain and frustration of the ammunition batches changing and then not working in my shooting platform - as it is unviable to reload .22LR it became clear after thousands of rounds of testing that most rimfire manufacturers actually produce very consistent ammunition and it is our own individual barrels that do not match it - after trying to get a tuner for my barrel in the uk - custom made to fit without gunsmithing it became clear that was a non starter - so I decided to do something about it and started to test and build a local product to benefit all ! - All I can say is the results speak for themselves.
Please see the result of the final products after exhaustive testing.
Please feel free to contact me with any questions
Regards
Johann
