What effect does shooting from a bench with the muzzle directly over the bench top (not out over the front edge) have?

Does (or can) it mean change of impact or larger groups?

Off hand, I would say none, because the bullet has already left the barrel. I assume you are referring to the effect of muzzle blast?

I don't know if it has any affect on the bullets flight but, it has a definite affect on the neighboring shooters. In fact, in both the NBRSA and IBS rule books, it states that the muzzle must be forward of the bench top.

Yeah LOL!

It sure does clean the debris off the bench

Pictures that I have seen show some gases exiting before the bullet.

Hmmmm... I'd like to see those.

as you fire, gases are building up around the bullet and befor the bullet can completly seal off the bore, gases escape around the sides of the bullet and exit the muzzle first. not to mention all the air the bullet is pushing out.

well, thats the theory anyway

Resurrecting an old thread, but this could make an interesting test. Anyone care to?

No!

Better yet, start a new thread about barrel break-in!

NAH! Using Sierra matchkings for hunting! Now that is a topic! Or, using Sierra BlitzKings for Benchrest.
