Sorry, I mis read . I must be tired.I really do appreciate you guys helping me .I asked the same question on the trad.muzzleloading forum on the gun builders bench and only got one reply.And he was more worried about the thin wrist of my rifle.
dont confuse the traditional muzzleloading forum "claudes place " just a forum .
with the traditional muzzle loading association forum which is part of an association for the support and shooting of traditional muzzleloaders of a pre 1900 design .
there are allot of very qualified builders that post on the TMA forum from all around the world .
post your question there and i know you will get alot of answers as well .
Another good spot would be the American long rifle association .
Fi you look into this subject long enough I think you will find that really this issue with the drum bolster is much the same as that of the flint liner . Some folks have some very strong feelings about both , their reasoning very logical . However when one considers the design , how long its been around you find failures are very small to not existent when dealing with rifles that have been properly built and maintained
