JCalhoun, My '03 had a peep(rear) mounted on the right side in front of the bolt handle, with the "shank" of the Lyman-type peep extending vertically down into the stock, with 2 vertical screws holding it in place. The threads remaining in these holes look very good. When I removed the peep, it left a "void" in the wood where the peep had been mounted. Is it possible that this gun was one of those types that you mentioned in an above post? Or, is it likely that these holes were drilled and tapped by a gunsmith during the sporterization process? I'm a little concerned now as to how well the machinist did my drill/tap job. I had him do another job for me at the same time, and that was "pathetic" Any suggestions for checking the quality of the work before I attempt to sight it in?
Your rifle will have been drilled & tapped by a gunsmith when it was sporterized. The military D&T rifles are few and far between and highly prized by collectors.
If your machinist d&t'd the top of the receiver I would try to lay a straight edge along the holes to see if they line up. This the biggest issue with this type of job. Then you could try to get a tap of the correct thread size/pitch for the screw being used and see how well it will thread into the holes.
This is why I don't recommend that anyone sporterize a military surplus rifle unless it has already been modified anyway. The trouble is that if the work is done wrong, you are out of your money and now you won't be able to give the gun away.
BTW, I should have thought of this sooner, what make and serial number range is your '03? If it is a low number it could very well be unsafe to shoot.
Anyone who shoots a sabot bullet has had the problem with loading the next round with a dirty barrel we have all struggled with it.
Between muzzleloader shots I have done some research and testing on my own to find out what works for me for the next shot. I have been using a product called bore butter and when the muzzleloader is just sitting around I leave it caked in the barrel for protection. Have also found that if I lube my sabots with bore butter they really slide nicely down the barrel....
