.300 Winchester Magnum is another option, but you need to weigh the advantage of easily available factory ammunition against a case which requires the bullet to be seated too deeply in order to function in a standard length magazine. When I say "too deeply", I simply mean that a long bullet protrudes far enough into the powder chamber of the cartridge as to reduce its case capacity.

This complaint, and the related complaint that the neck is so short that accuracy is affected, have been around for decades. However, the cartridge produces plenty of speed even if the bullet does protrude below the bottom of the neck. Also, the accuracy is sufficient for a Secret Serviceman at the 1000 yard match at Quantico to shoot a perfect score plus something like 20 additional Xs (if at the end of a target string a 200-20X is recorded, the shooter continues shooting until something other than an X is fired).

In my personal experience, I have never found the 300 Win Mag to be lacking in speed or accuracy.

Take care, Tom
