"this kit was expensive ($1400)and suppost to be premium'
That is a pricey parts set, especialy comsidering what yopu have told of it thus far, I do not mean to rub your nose in it so to speak but it does reflect the need to get as many references and do as much home work as possible when gettIng a gun or parts, A while back I saw a write up on a coule of a guys guns that were very decieveing from a historical perspective and this guy was asking about $2000 for a French Fusil (Tulle) with a "correct" curly maple stock :shocked2: I was kind of surprised to see a builder in this level with so much inaccurate information about the various guns.I hope things work out for you with your parts and also hope that others will maybe learn something from it, I constantly harp on this issue and this is the reason why, good luck I think it will all work out in the long run, as most have said the first few inches is where the concern about shallow barrel walls is generally an issue, whe proofing the barrel make sure it is well secured as one ,member mentioned they can get away from you and can be damaged in the process which is a shame if a barrel is proofed OK but danaged from banging into something solid and getting bent
