Personally never thought much of the flutting done on barrels. Always doubted the supposedly advantages tooted by the scribes. Never thought of what your proposing too do so that adds another dimension too disadvantages. Recently read an article in latest issue of Varmit Hunter magazine whereby the author made some claims about undesirability of flutted barrels. Some of the things he mentions I've experienced so tend too believe the article.

Since there's no responses too date suspect maybe no ones done this either. Maybe you'll have too do the experimenting and report back.
