With only one eye you have a harder time judging distance and picking up moving targets. More practice will help. How many times have I said "practice", probably enough that you got my point.. Did you loose the other eye recently enough to know if it was also your dominant eye.
Nope - not recent. I was born with ~ 95% sight loss in my right eye.
As a result, I have & never did have any depth perception. Yes - hitting something moving is and always has been erratic. Not only shooting, but, hitting a baseball, catching a ball & stuff like that. I suck at that stuff too.
However - if it sits still for a fraction of a second, I "own" it.
I shot a round of sporting clays once and at one station they toss two birds straight up in the air at once. That was tailor made for me. They hit the high point and hung for just a split second & I smoked them both. IIRC, I scored 8 hits all told - pretty much suck city...it was a lot of fun though.
Re. a .22 - I have an old Marlin/Glenfield model 60. (Decent gun). I also have a Browning .22 lever action(pretty gun but nasty trigger) & my wife has a Winchester 9422 Trapper (Really sweet little gun - but -it's hers & I don't get to touch it all that often).
I have thought about getting a Henry & putting a tang sight on it.
I go round and round w/that idea.
I do also have a Marlin Cowboy II in .38/.357 that a tang sight would just be perfect on.
Since I also handload, shooting that is on the cheap side.
Re: equipment - well, I have two Winchester Trappers, one in .44spl/.44 mag and the other in .45LC. - a Ted Williams (Sears) brand Wincheter 94 in .30/30, the .22's mentioned above and a Winchester 670 in .30/06.
I handload for the Trappers so ammo is on the cheap there.
The other two the .30/30 and the .30/06 - I very seldom - if ever - shoot them because of the recoil. I just don't get any enjoyment out of getting my shoulder pounded.
Bottom line here & I guess it's one everyone has stressed is - practice, practice, practice.
Stupid question here - would dry firing help any?
Finding a place to shoot a rifle around where I live is very problematic.
The nearest place to shoot one is an hour away.
W/gas prices near $4.00 a gallon, that makes it about a $12.00 round trip.
Since I retired, my "fun budget" is about $80.00 a month so going once a week would chew up over half my budget in just gas alone.
Once a month would be more realsitic.
