I’ve sold a fair amount of my rifles. Posterior cervical fusion C2 to T2 limits recoil tolerance. The only rifle I miss is a 416 Taylor. It is a wonderful cartridge and easy to shoot and load for. Shoot lots of cast bullets at almost full speed. The Speer 350 grain is an outstanding performer as is the hornady 400 soft.
The Lee dies have a tapered expander to neck up 7mm mag cases and make something useful out of them.
Killed a pile of bison with it, mostly two year old heifers at 1200 pounds. A few bulls in the upper teens weight wise. Just puts their nose in the dirt now. Somebody sent me a handful of 300 grain bullet made from 40 s&w cases swaged. Killed seven heifers, all head shots. No exits so a pretty soggy bullet. It was a fun rifle
