When Remington stopped making the 660's I made cases from 7mm RM and 338 Win Mag just to see how difficult it would be. It is easily done. In retrospect cases are still easily found.
I have a 1x3 Weaver scope on mine.
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally
