The Sauer 505 was built around one clever idea: one rifle, many calibers. This factory 300 Win Mag barrel, carrying manufacturer part number 80117170, is the piece that makes that idea work for hunters who want a serious magnum on the same action they already trust. It comes cut with a 9/16×24 muzzle thread, so mounting a brake or a suppressor is a quick job once you match the right device to the pattern.
Sauer builds these barrels using the cold hammer forging process the company has leaned on for years, a method that produces excellent bore concentricity and long service life. In 300 Win Mag the platform runs a 1:11 twist, which stabilizes the heavier .30 caliber bullets this cartridge does its best work with, from long-range target loads to tough bonded hunting bullets. Magnum chamberings on the 505 typically ship in a 24 inch length to wring full velocity out of the case, with a shorter option available depending on configuration.
The 505 barrel is secured to the front of the action with three numbered Allen bolts and a locating lever. Back the bolts out in order, drop the lever, and the barrel lifts free. That modular design is the whole point of the system, letting you run a lighter medium caliber for deer and drop in this 300 Win Mag tube when you're chasing elk or reaching across a canyon. Keep in mind that jumping between cartridge head sizes may also call for a matching bolt.
The 300 Win Mag is a hard-hitting round with real recoil, which is exactly why that threaded muzzle earns its keep. A suppressor or muzzle brake takes a good bite out of the shove and makes range sessions far more enjoyable. Pair this barrel with the Sauer Universal saddle mount and your optic returns to zero after the swap, so you're not burning ammo re-zeroing every time you reconfigure the rifle.
This is a factory 505 barrel designed to interchange on the Sauer 505 platform. It mounts to the front of the action with three numbered Allen bolts and a locating lever. If you're moving between different cartridge head sizes, plan on a matching bolt to go with the new chambering.
The muzzle is threaded 9/16×24, which fits a wide range of American-pattern muzzle brakes and suppressors. Just confirm your device matches that pitch or grab the correct adapter. With a magnum like the 300 Win Mag, a can or brake makes a noticeable difference at the bench.
The 505 runs a 1:11 twist in this chambering, which handles the heavier .30 caliber bullets the 300 Win Mag shines with. Magnum barrels on the platform are commonly 24 inches to get full velocity, with a shorter length offered in some configurations. That combination gives you strong reach for elk, long-range targets, and open-country hunting.
That's the entire appeal of the 505. One action can wear a medium caliber for everyday deer hunting and this 300 Win Mag barrel when you need more punch, so you keep the same trigger, stock, and feel across the board. It saves space in the safe and keeps you familiar with one rifle.
