tangolima said:I don't do factory ammos, except.22lr, and even that I stick to one particular make and model. I have my own steps to develop a load. I am not changing that. The tuner is just a final polish, which will probably cost 20 extra rounds. If it helps at all, I will do it.
All I was saying is that barrel tuners need constant tuning. Any time you open a new brick of rimfire ammunition, canister of powder, brick of primers, or box of bullets for your hand loads, you're going to need to test your tuner. They are not a set and forget accessory to your rifle.
Here is a guy doing the same thing you're talking about with a self timing brake: https://youtu.be/wXxSySAw4E0
Here is an argument against tuners: https://youtu.be/NvzU1HiCKj0
This guy shoots F-Class and while some of his comments wont apply in this situation, some will. I'm neither for or against tuners, I said I believe they work.
Browning and Winchester both had the BOSS tuner at one time, but they had to be constantly adjusted every time your average hunter bought a box of ammo for deer season. They also didn't really improve an average deer hunters chance of success, and since most people didn't understand the purpose of the BOSS they thought they were ugly and undesirable. So the BOSS simply went away after a short time.
