Re-profiling a barrel
Guys

What (if any) are the issues and risks in having a barrel re-profiled, it will go from a #3 to a very slim featherweight style

Thanks

Sometimes internal stress can cause th barrel to bend and you can end up with a curved bore. Only once has a barrel done this while I was cutting it, and for reasons beyond me it straightened out as I continued to cut it.

Try to look unimportant. Your enemy might be low on ammo.

I hear that cut rifled barrels tend to warp the least.

FISH!!

Heed the words of Winston Smith in Orwell's 1984:

"Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right."

Most modern barrels are properly stress relieved and warpage isn't really an issue. If I get a barrel from any manufacturer which does warp noticeably, that means it is not properly relieved and I simply avoid that maker in the future.
Barrels I have turned with no issues include barrels from Atkinson, Buhmiller, Douglas, Hammerli, Hart, Lilga, Lothar Walther, McClennan, McGowan, Remington, Ruger, Shaw, Sherer, Shilen, Smith, Winchester, and some others I can't think of.
Interestingly enough (I guess) some of the worst barrels were cut rifled (Bauska) and some of the best were hammer-forged (Winchester). Regards, Bill
