I saw the comment below, and thought I would start a new topic.
"This may be a little off topic, but in reference to your statement about pulling the trigger when lined up... Do you typically try to time your trigger pull with the POA float so the trigger pull would happen just before your sight floats back into the black?"
35 years ago I spent a Saturday with three gentlemen on the Marine Corps Pistol Team. They gave great tips and coaching on offhand (one handed) shooting of targets with a pistol or revolver. There is really no difference in shooting longrifles offhand or one-handed offhand handgun shooting. The basics are the same.
They gave several pointers I will share with y'all.
1 - When you can see the corners of the front sight clearly, then you are focusing hard enough on the front sight. (For me, that means a baggie of reading glasses for any distance to the front sight. Yes, target will be fuzzy, as it should be). I cannot shoot squirrels anymore with open sights as they blend in with the trees.
2 - Accept the wobble. Everyone wobbles, often in a figure eight pattern. If you try to time it, and snatch the trigger as the sight goes by, you'll miss. Accept that on a given day your wobble is "X" size, and that is how big your groups will be. Most of the time the front sight is somewhere in the middle of the wobble zone, so your actual groups will most likely be smaller than the wobble.
3 - Ignore the shakes - On certain days you'll have the shakes (as opposed to wobble, or you may have both). It could be coffee, lack of sleep, the phase of the moon. Who knows. The shakes do not show up on target. One of the Marines said he won a hugely important match and his hand was shaking like a terrified puppy in a hurricane. The trick is the shakes mess with your mind, so you have to stuff that worry down and ignore it.
4 - Trigger press - When offhand you HAVE to slowly increase pressure and let the trigger release when it wants to. Surprise break some call it. Letting the trigger break while maintaining sight alignment and not moving the gun off target are three of the four keys to offhand shooting. The other being accepting the wobble. Again, if you try to snatch the trigger as the sight goes by, or time it, you are setting yourself up for unhappiness.
5 - No need to "death grips" a gun. A good firm hold is needed, but not a death grip. Death gripping leads to shakes, which erode your confidence.
6 - If shooting offhand, close your eyes and bring up the firearm in a natural position for your body. Open your eyes. If you are not aligned with the target, shuffle your feet until you are in alignment. Repeat. If you don't do this, you natural muscle structure will tend to pull the gun to one side or the other in recoil. For me shooting a handgun offhand, my arm is almost directly out to the side....90 degrees from where my chest is facing. I never would have known that until told.
All of these tips are most important with offhand shooting long-barreled muzzle loaders. Why? That ball takes a long time (relatively) to exit the muzzle from when you break the trigger. Lots of room for the rifle to move during that time. Keeping it on target, with aligned sights and a trigger break that does not disturb the gun is the key.
I hope these tips help someone. I am sharing what I learned that helped me.
