I tried to upload pictures, but my photobucket account is actin' up. I'll see if I can find another photo posting site.
What happened was that I measured from the wrong side of the stock when I cut the ramrod groove in. Barrel is centered from one side, and ramrod from the other. When I drilled the pilot holes from the barrel inlet to track the ramrod drill bit, I noticed that they weren't centered (really only noticed in this at the entry pipe location). I drilled another pilot hole at the entry pipe from the ramrod groove to the bottom of the barrel inlet, these holes are a little less than 1/8 inch apart, from the centers.
I was able to cut the ramrod groove a bit deeper near the front muzzle (I also switched to a 3/8 ramrod, which allowed me to move it over a bit as well), and got most of this out, but the groove now is on an angle, since I couldn't move its location in the forearm.
My thoughts on this, so far, are that I could make my entry pipe so that it is centered on the stock , draw a line from that to the muzzle, and see where that puts the ramrod (it's hickory so it flexes a little). I can then remove some wood from the tight side and replace some wood on the wide side, and re-cut the groove. If I place the entry pipe centered, I can widen the entry hole so that the rod doesn't bind and the pipe will cover this slop.
I'll try to get pictures for you in a minute.
