I have to say the process drove me crazy I was not prepared mentally for wasting this many rounds at 100 yards... it broke my brain
The biggest bitch was, before I started my test group looked like this:

So I am starting from a point here, and then the groups were going big, smaller, not quite small enough, bigger, it drove me nuts. I hated it playing with it.
I threw a ton of fliers too that made me hate it even more and question the entire process. Is that ME or the tuner doing it, is that two in one hole and a 3rd, is that group good enough or should I try more. The mental aspect of this process should not be overlooked.
Then to make matters worse, my suppressor came loose twice, once the can, and it's an OSS Reverse thread, I think initially there was some contact I missed. Then the brake loosened up so I took it off and started over.
Another brain breaker, trying do to it on a 8x11 sheet of paper. I did not go to my range, I met Chris Way at a local 200 yard range near Denver. I had built a target at my range, like many above, used a 3/8" orange pasty, spread wide apart. Doing it on a single sheet made it a mess personally. I hated it.
Now all that said, that is all me, I can see these working but at what point, The idea is simple enough, David Tubb talked about it with his brake, moving the self timing brake back and forth to tune.
So it actually lends to ideas.
I shot way too many rounds for about a 1/4" increase, so in my mind this is the perfect factory gun fix, or seating depth replacement. I know speaking to a Palma Shooter they talked internal Ballistics a ton. Chasing lands, chasing barrel, to me here is where the tuners would shine.
I think the thing that killed me mentally was when a group got bigger. Of threw a round farther than before. Almost every group was just one round out there, 90% were two round in one hole, one round out, so you are Constantly questioning your own shooting. E Blah I hate the amount of ammo I was shooting at paper.
But I plan on moving forward, I think I might cherry pick rifles to use, my Bartlein barrels don't really need it initially
And for me not having all my kit with me, no spotter, you have to literally walk down every single shot. I had actually missed a perfect stopping point because from behind the rifle I didn't see what I thought I did, (didn't have my prescription glasses with me either, total operator error, self induced clusterfuck ). so I could have been finished in like 18 rounds and been happy, instead of 68 rounds ... and stopping.
