The Remington Model 8 (predecessor to the Model 81) was accurate enough to be used in the 1912 and 1920 Olympic games. In 1912, the U.S. "running deer" team used Model 8's in 30Rem to bring home a silver medal. (Henwood, 260).
They're not target rifles though, but some are capable of 2" groups at 100. They've got a 2 lug rotating bolt. There's actually 3 main springs in the rifles. In the barrel jacket you'll find a buffer spring, which is short and stout, and also the primary recoil spring. In the stock there's the action spring which forces the bolt & carrier back forward after each shot. Springs don't usually need to be replaced. I've got a 107 year old Model 8 still cranking out brass all day with original springs.
300Sav, along with the 35Rem, are known as the heavy (shoulder) hitters. If you want to know more info than you'll find anywhere check us out below...
