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.

DITTI! It's a crap shoot at best.

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

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
