I am new to long/precision shooting and am excitedly and patiently awaiting a I.O.T.A. to improve my technique with dry fire pratice. I have found that dry fire pratice helps not only the muscle memory for accurate shooting, but also allows you to see what your doing wrong when you not shooting accurately. My question is regarding dry firing indoor once I recieve my I.O.T.A. Should I be using snap caps, or should i save my money? I know from my dry firing at the range that the majority of my mistakes are from handling of the rifle and trigger and do not know if the reaction from the snap cap recoil impulse.
