I'm so sorry about the four misses. The camp stool has been a lifesaver for me. Since I have a 45 degree angle on my scope, I use only the two rods for the stand. When I look through the scope, I lean downward and let the stock butt rest on the stool. Pick up a copy of "The M1 Rifle" pamphlet from the NRA. It will give you accuracy tips for your rifle. I wear combat boots for the standing and the jacket and the mitt type glove. Your shooting stance shouldn't look like you're hunting. The rifle should be over your hips with a slight rear bend. Study that Jim Owen's website. First get your natural point of aim by closing your eyes. When you start go to the target, I start from the left side and gradually bring it to the black. I practice dryfiring with a scoped rifle just so I can quit hitting the trigger. I think that's what you might be doing. I accidently got in the habit of getting excited when I had a good sight picture and hitting the trigger.
You'll notice that the rifle is over my hips and my head is as level as I can make it. If you bring your head down to reach the rifle, It throws your equilibrium off. My right elbow is high to lock in the rifle. This is from a Garand seminar beause I wanted to give the guy with the blue hat some company. I still learned a lot.
Good stuff. I watch the experts & masters and try and copy their style - but I'm not always sure as to the whys & whens of what they do. I think the books & pamphlet you have recommended will help answer those questions. I got a good spotting scope with the 45 degree angle, got the mitt and jacket. I still need a good sling, I'm using the stock web sling right now. I usually shoot 70-80% on the slow standing, yesterday just wasnt my day.
