[QUOTE="Centre Punch, post: 82880, member: 3048"] ds, I understrand your principle of an integral shrouded muzzle and it sounds feasible, but i dont think it would be very practical. Yes, a counterbore and a crown could be machined by any skilled smith and the out side diameter threaded for some kind of device but i think it would be somewhat "flimsey" and easily damaged, also the barrel harmonics may be compromised regardless of a barrel tuning device, posibly renderring the barrel untunable. I think the term crown is not being used broadly enough here as crowning is the operation of finishing off the muzzle of the barrel. Let me assure you, barrels are not just "cut off", they are faced perpendicular to the bore effectivly creating a 90 degree crown. The crown only needs to be a small accurately machined surface emulating from the bore creating a true and even juncture between the bore and the muzzle This also applies to recessed and 11 degree crowns, which must also be machined accurately to the bore. If this facing is not perfectly perpendicular, gas will escape unevenly past the bullet on exit from the bore, causing an imbalance and bullet upset. Deep threads will not effect a crown, although they would weaken the muzzle of the barrel if they to encroach to near to the bore, similar to what i said earlier regarding your extension. But Hey! dont let these comments stop you from trying this principle, after all, without experimentation where would we as shooters be today. If it works, i will be the first to stand up and cheer.
