Not sure if others are aware of these. Wild West Guns in Anchorage Alaska sells BLR takedowns for about $2500. Theres a used .416 on "Accurate Reloading" forum for sale for $1800. My gunsmith put a Shilen .375 Ruger barrel on my .300 Win. mag. takedown. I love it, MOA accuracy and legal for african dangerous game. I shot quite a few animals with it, incl. a big cape buffalo. For sure the rebarrel job voids any warranties!
