Got a 300 RUM Heavy varmint threaded for a Remington 700 with muzzle brake. I just picked this up from my gun smith, I had it borescoped looked excellent so I went ahead and had it rechamberd. Barrel has no rounds on it since this was done. Honestly I do not remember the manufacturer of this barrel got to many but here are the specs, 27in finish length 29.5 length with brake,1.25 straight taper to .900. Had all of this done for a custom build but went with my favorite 338 instead. I would be happy just to get my money back for the chambering. $250 shipped. Thanks. $200 shipped
