With some lower cost ammo the bullets are not crimped tightly in the cartridge case. During firing the recoil impulses could (and do) cause such ammo to result in bullet setback into the case.
Do you know of any data showing how much setback would be a concern? Or what is your opinion on setback?
Will setback cause a velocity increase enough to be a concern, since this means higher chamber pressure as well.
Or do you think chamber pressure and velocity are mainly controlled by the powder loading and setback shouldn't be a concern.
After all, in a muzzle loader the bullet is rammed tightly against the powder to achieve maximum velocity. So why aren't regular cartidges made with the case full of powder so no setback can occur?
I don't have a chronograph so I lack any data to contribute. But I do see setback with some lower cost stuff like what comes in ValuPacs.
