I have been practicing for a while and a think my shooting technique is getting pretty good(im only 16). Im not recoil shy and i dont flich, although i pull shots alittle bit every once and a while that i think is more of a target panic thing and i usually know when i do it before even looking at the target. I have one problem i cant seem to do anything about and would like to know if there is anything i can do or if it even affects my shooting. When i dry fire my rifle, i blink right when the gun snaps. I generally dont really move the gun, if i do its very slight, but i was wondering, if i blink with the snapping of the rifle, are my reflexes delayed enough that by the time i start to move the gun as i hear it snaps ,has it already gone off, or if a slight blink just doesnt really make a difference in the point of impact. Does anyone else do this and what if anything have you done about it. Also, although this is really a differnt topic i thought it was related enough to put together. Do upgrades that reduce lock time such as a faster firing pin make a significant enough difference that it would allow me to shoot more accurately and allow my shot placement to ingnore tiny movements i might make when the pin snaps which are magnified at long range(i guess thats whats causing the blink). Are firing pin up upgrades, faster firing pin, ect. worth while upgrades and how much would i be looking to spend on something like this. How much better are aftermarket firing pins, ect. than the factory rem 700 setup? Thanks.
