I understand but there is literally no way to prove they work to anyone else. I have struggled with them off and on for years. Back a few, Anschutz USA was clearing out some 54-18 actions do the Custom shop started creating 54-18 benchrest repeaters (yeah an oxymoron). I have their #1 rifle and I told Steve B that I didn’t need one. I was seeing some vertical so I bought a Harrels and put it on. Cleaned it up. Some ammo was more affected and as I buy cases, I live with the results. The thing is you can’t prove that you either didn’t lie about the good or that you didn’t fudge the bad. It is something a person has to be interested in and try’s for themselves.
I think most people would agree there is discussion and testing to be done around tuners for reducing group size.
The issue all comes with the ignoring of ES, as ultimately this is what determines your accuracy at distance.
Almost every groups you will see is wider than it is tall (if no wind present), meaning the ES is what is dictating the ultimate accuracy.
My limited testing mimics Jajas extensive 50 @ 200 testing, which basically shows group size is ES at distance, when pluging the minimum and maximum numbers into Strelok you'll get a difference in drop that more or less equals what you see on target.
I appreciate you can't change your ES, but that's the point.
If you can't get a stable supply of ammo that has a low ES, shooting at 200yards + is just a recipes for frustration.
If your groups at 300yards are 8" tall due to ammo ES, then trying to do long gong on targets that are 6" or 4" means you are just gambling that most of the shots will be on target.
If you are trying to shoot targets that are smaller than what your rifle and ammo is actually capable of, then expect it to be frustrating once you start getting competitive (or overly competitive).
It's the difference between the NF ELR challenge and a 1000yard 22lr trick shot.
NF ELR is within a distance people can be expected to make consistent hit's if the shooter gets the fundamentals and environmentals right.
Where as a 1000 yard trick shoot is always going to be a case of just shooting until you get lucky, or you shoot at a big enough target that it doesn't represent any real form of accuracy.
Some people may enjoy the "trick shot" style and that is fine, by sounds like the OP was finding it frustrating, hence my comment to limit shooting to 200yards. I know I started getting frustrate in shooting matches starting out with CCI Standard, as the long distance targets became a luck thing rather than skill, and you just had to shoot until you got a hit.
