get a sheridan function gauge, too. it is sized to the grendel chamber and you can drop your cartridges into to check them before loading one into your rifle. it's a great tool! It's one of the tools that helped me realize I had a chamber issue in my barrel. Ammo fit perfectly in the sheridan gauge, but would get stuck in the barrel's chamber.
