Has anyone here shortened and re-crowned a barrel? Has anyone cold-blued exposed metal on a rifle? I am contemplating shortening my Weatherby Vanguard S2 barrel from 24" to 20" or 21". Ole Larry Potterfield from Midway USA makes it look so easy on his videos, but I am nervous that I will ruin an accurate rifle. I hunt in Western PA where it is hilly and densely wooded, and almost all shots are under 100 yards. I am either in a stand or helping with a drive, so a more compact rifle would be ideal. As always, thanks in advance for your help.
