Jim, thanks for posting the findings of a few of your guns. Obviously, each gun is an individual, with its own set of dimensions. My thinking is the pitch is specific to each gun and has to work in relationship to the barrel. Although I mentioned the wall measuring system, my brother and I use the top of a flat work table and a carpenter triangle and a wood wedge. Lay the gun flat, move the wedge under the barrels till the buttplate is 90 degrees and then measure the table top to the muzzles. Knowing the desired pitch just move the wedge till it has the barrels X inches as desired. Then move the triangle to to your wood adjacent to the buttplate and mark the angle on the wood to be cut. I think all guns are to each its own, and the pitch is just a part of it. But I think an important part and will continue to explore the writings on the topic. Thanks for all the comments. Randy
