Re: Close your eyes.....
Don't shoot off a bench unless you are sighting in, or plan to shoot in a bench rest match.
Concentrate on the sights and target to the point that your peripheral vision is blocked out. concentrate on staying on target through the whole process and even for a few seconds after the shot. Till the smoke clears and you can see the target again. You won't even notice the hammer fall and flash. It seems to be easier when shooting at a small silohuette like a 6 inch steel plate at 50 yards. It doesn't take great accuracy, but shoot and hit until you can do it 10 times in a row. Then move it back to 75 and repeat. And then 100. It really shouldn't take all that much practice. perhaps 100 shots to become proficient on the deer vital size steel plate at 100 yards.
It is infinitely easier if you already have the upper body strength to hold the gun at the shoulder without fatiguing. I lift sacks of feed, bales of hay and chunks of firewood every morning and every afternoon. Some folks due to their jobs and life style, would have back aches trying to shoot a TC Hawken for 50 shots.
