Just got done drilling the barrel pin holes in the tenons on my Traditions Ken. rifle kit. Front one was perfect, couldn't have done better with a CNC. The back one lined up right but the drill walked a little (those tenons were harder than I thought ) and it ended up going in at a slight angle. The hole on one side of the stock is about .100" lower than the other. Not really noticeable, but my in my perfectionist/ocd head it's glaring. Best to just leave it and move on , as any attempt to "fix" it will only make it worse, as my past experience has proven. Oh well, it's my first kit and it's all part of the experience and learning curve, nothing ventured nothing gained. At least I got the holes dead center on the tenons, so I can measure better than I can drill. Carry on.
