I was going to install this barrel on a pre 64 Win #70 in .340 Wby. After getting it on the receiver I changed my mind and used a #4 for the extra weight. (good move on my part ). The barrel is 26 inches long but you will still need to cut 1 inch off the muzzle. No chamber but is threaded and coned for the 70. The 1/4 rib is a Dakota for this barrel but has not been fit. Take both at $180.00 tyd.
