Spacecoast;
I have been competing in bullseye for a little over 2 years now.
Believe me that when I say that I am no expert, I mean it.
Although I do hold an expert card
I have gotten some good tips over the last couple years from some very good shooters.
A couple times a month I shoot along side of John Zurek and Steve Reiter.
What I have learned from my experience and some tips from the above high master shooters.
If you think about it, it is a real easy concept.
It is just doing it that is the problem.
Have a consistant grip on the gun.
Align the sights, and I do mean ALIGN the sights.
Accept your wobble area of aim, do not fight it, it is what it is.
Press the trigger in a way that it does not interupt the sight alignment.
If you do the above, most shots will be better than the 9 ring.
There is a lot more involved than what I wrote above, but it is the nut shell.
#1 being TRIGGER CONTROL.
I shoot a S&W M41 with a Clark barrel and an Aimpoint Micro H1 red dot.
Also a Rock River .45 with a 4 dot Match Dot.
The above have dots on them but the principle in shooting is exactly the same.
My iron sight guns are a 6" Colt Custom Python used for distinguished revolver.
A Dave Salyer built Beretta 92FS for EIC ball matches.
My best advice is practice a lot.
Focus on the front sight.
Do not worry about your wobble area.
Trigger control.
I use a sub six hold using iron sights with the Python, 92FS, IZH46M air pistol and TOZ 35 free pistol.
It works if you spend the time to get good at it.
If you have any specific questions, please do not hesitate to ask.
