Ah. Try that with a rifle.
I do, it just takes practice, its actually harder with a pistol
(Both hands are straight out in front, being more off balance holding a weighty item,
as opposed to a rifle being in your shoulder, held with right hand midweight plus at the fore end
Providing a more balanced and more secure 3 point contact)
I can't do it with a 15 lb heavy barrel rifle of course,
But I do the same exercise with a long barreled .22
it took a couple months to get there
---------------------------------
the thing about it is, many people just give a few basic fundamentals then tell you to go out and practice a lot
but nobody teaches any techniques to "Gauge" yourself otherwise or good ways to practice at home without expending ammo
dry fire is great but how does a guy know he isn't moving while dry firing
which is why I started using an indicator to gauge my movements until I could control them to that level
anyone could do it
.001" movement translates to approx 1/10th inch at 100 yds with a rifle
----------------------------------
After using my methods I began to be able to start splitting cards (at 20 yds so far)
thats actually only difficult because they are so thin you have to move from side to side to see part of the face,
then barely being able to see that thin line and remember where the card is, then aim at the spot where you remember
