Rounds for 'dry firing'???
I would try fireing my rifle without ammo and concintrate on keeping my eyes open dureing the process. It was recommended to me and I am passing it on. It seems to work for me. Check with a local gunsmith or your rifle manufacturer to make sure it won't do any damage to your personel firearm.
Aren't there cartridges out there for just that purpose? Training?
Wouldn't this preclude causing any damage to the rifle?
