Has anyone converted a 7-08 barrel to a 7MM BR ? I am thinking about trying to convert a barrel to 7MM BR for a youth rifle. If it will work, it should be a good rifle for a kid to shoot. The 7MM BR is known for very little recoil and accuracy. Its been a favorite for the serious target shooters. Its seems like it would be simple. Making a chamber adapter to shorten the chamber length is all that it should take. The case size (except length) is the same as the 7-08. The factory extractor/ejector wouldnt have to be changed either.
