G'Day Wood Beef,

Sorry for the delay (in remembering and responding), with the info from Page 438 of the Speer #9 reloading manual.

It specifies the following Four (4) rifles, chambered for .308 Norma Magnum and their twist rate;

Musketeer and Schultz & Larsen = 1 in 10"
Browning and Husqvarna = 1 in 12"

Sorry WB, I cant help you out with who the manufacturer of the Musketeer brand rifle is/was???
But rest assured, one of the rusted on NE forum participants will know!!!
Well maybe???

Edited by Homer, Sorry, I just re read this thread and Long Island has already addressed and answered this!

Hope that helps

Doh!
