Funny you mention an M-40 for a couple reasons. 1, I never got to fire one while deployed. It was introduced as I was rotating back to the World in March 1967. ( I used the fine Win. Mod. 70 In 30/06) 2, I am in the process of getting a Remington version of one In 300 win. Mag. ready to shoot. We both had the best jobs in the Marine Corps. Yours was far more detailed than mine for sure. Both were important in their respective descriptions.
Just a quick Hint for you. M40A6 (Or A7 depending on who you ask) in 338LM would easily accept 300 Win Mag.

In fact 1 or 2 might exist in such a configuration.
