I love threads like this, like we're sitting in the clubhouse after shooting and talking it over.
A couple things....
"....Straight and flat....." is where plenty of shotgunners would like to be. One can raise POI by adding cardboard to the top of the comb only.Once the best height is ascertained, you can duplicate it in Neoprene or wood.
Or, loosen up the stock bolt until you can pull it back a little, then insert a shim at the bottom nigh the trigger guard. Something like a business card folded once for starters, pattern and adjust as needed.
HTH...
Hi Dave. Here I was thinking that Weatherby and I were spending too much of the board's resources on discussing out thing. You mentioned shimming my 870 up with a matchbook or something, as well as raising the poi with cardboard or, if we want to get fancy, moleskin from WalMart. I have just never gotten around to trying it. I think I will be bold and experiment with the old girl. She may not be as purty as Frankenstein, but I think she is showing "character".
Talking about character, after Weatherby left I wandered way down to the far end of the skeet line and got to meet a couple of characters. One had a 1100 and the other a Winchester 1200. I think that is what he said. The bluing was nearly worn completely off of their receivers. I donn't now aby the Winchester, but the 1100 was a fixed choke.
The guy with the Winchester was having a bad day, but the old guy with the 1100, who tachnically was doing everything wrong, was smoking them. Even the two he shot with a couple of my reloads. The reloads of his own that he was shooting was a nightmare. I think that they were from his first attempts with reloading, as he gave me a couple good looking recent reloads to try.
One was leaking shot thorugh the crimp hole, so he had plastered it with mud. Another he closed up with a cigarette filter that he picked off the ground. (That was a miss. I wonder if the filter blew a hole in the middle of his pattern.) I told him that he would get a better seal if he mixed the muc with some road apple.
Regardless of what I might end up with for an O/U, it makes me think that a shooter is incomplete if they don't have even a very well worn 1100. The only gripe this guy had about his was it is getting difficult to get parts for it. I noticed it failed to cycle a lot, but I think that may have been due to the reloads he was clearing out.
