I have a Model 70 Winchester in 7mm Taylor & Robbins Magnum (a predecessor of the 7mm Remington Magnum), which was built for my late friend Crawford Hollidge, of Spin Tru bench rest bullets fame and writer of the Ernest Stuhlshuter column in Precision Shooting. Unfortunately, Crawf was left handed, and I am not, so I had the barreled action re-stocked by Griffin & Howe back in the '80's, and had another barreled action fitted to the stock by T&R, which I then sold. The T&R chamber accepts 7mm Remington Magnum ammunition and is a tack driver.
