There are several people pulling barrels off 700 ML's to make .45 cal smokeless muzzleloaders. You could probably find an original .50 or .54 cal Rem barrel pretty cheap. This shop converts Remingtons to smokeless and probably has some take offs. http://smokelessmz.com/700ml.html

Also making an inquiry on Dougs Message Board forum will probably turn some up.
