Yes Eugen, you're right!!
Have to try the snap cap - live round mix- had not thought of that

I am probably flinching more than I realize.
BUT I do not understand why that makes a difference if the bullet is long gone when the recoil is felt. Flinching would then occur after the round has left the gun. Then the main factor is your sight picture when the firing pin strikes the primer- I would think....
