I know my opinion carries little weight here but I have a problem with the theory of positive compensation and the magic in a good tune being the barrels ability to compensate for velocity variations. I understand mathematically it can be shown to make sense. However, with the new super precision loading scales and the ability of people to load to single digit extreme spreads, why has this not proven to be a solution to short range tuning? Theoretically, if you have no velocity variation, positive compensation can do nothing for you.
Now let’s suppose there are variations in the bullets ignition to muzzle exit time but low velocity spread. I mean, how can there not be with the variables in ignition and friction? We just can’t measure it like we can velocity. Theoretically in this case, bullets exiting at a higher rising muzzle velocity, (or angle), would produce greater dispersion with exit timing variations versus a muzzle that was slowed nearer a “stop”.
Outside of computer simulation, has there been any measured confirmation that positive compensation is indeed happening??
