M77 RSM MKII

Did all the RSM magnums in 416 Rigby end up in 750- serial number range? Saw something on Gunbroker in 416 Rigby but with 780- serial number.

No...the earliest were in the 780- prefix, currently known from 780-07525 to 780-75288.

Mine is the 780 prefix & a great shooter.

The earliest production of the Magnum action and the Express models also had the front sling stud attached on the front of the forearm. Everybody decided this was not a good spot for such hard recoiling rifles so the stud was moved to the barrel.
There are also a few 750- (Magnum) and 760- (Express) rifles with the stud on the forearm, but by this time most will have the stud on the barrel.

Have one in 375H&H. Easily the best made production rifle I own.
