Description
Most magnum bolt guns come with 24 inch barrels, and once you spin a can onto one of those you're carrying a boat oar through the timber. CVA built the Cascade SR to solve that exact problem. This 300 Win Mag version wears a 20 inch barrel threaded 5/8×24, so with a suppressor mounted the overall package stays close to what a standard rifle measures bare. That makes a real difference climbing into a stand, swinging inside a box blind, or slipping through thick cover where a long rifle constantly snags.
Cascade SR Build Quality Where It Counts
The barrel and receiver both wear Graphite Black Cerakote, one of the toughest finishes going for shrugging off rain, sweat, and truck bed abuse. Underneath is the same Cascade action that earned the line its reputation, with a three lug bolt and short 70 degree throw that cycles fast and leaves plenty of clearance for larger scope bells. A zero MOA Picatinny rail comes on the receiver, so you can mount glass without hunting down bases, and a thread protector is included to keep the muzzle threads clean when the can stays home. Feeding comes from a detachable box magazine holding three rounds, with one more in the chamber.
A Stock Built for Real Hunts
The Realtree Advantage synthetic stock is fiberglass reinforced with CVA's grippy SoftTouch finish, which stays secure in cold, wet hands when a buck steps out at first light. The two position safety sits right where your thumb expects it, simple and quiet to run.
Why the Cascade SR in 300 Win Mag Makes Sense
The 300 Winchester Magnum gives you the horsepower for elk, moose, bear, and long pokes at deer across cut fields, and the shorter barrel trades a little velocity for a lot of handling. If you already run a suppressor or plan to add one, this rifle was designed around that setup instead of adapting to it after the fact. It's a purpose built magnum that carries like a woods gun.

Frequently Asked Questions
Is the CVA Cascade SR ready for a suppressor out of the box?
Yes, that's the whole point of the SR line. The 20 inch barrel comes threaded 5/8×24, which is the most common thread pitch for 30 caliber suppressors, and a thread protector is included. The shorter barrel keeps the rifle balanced and maneuverable once your can is mounted.
How much velocity do I give up with the 20 inch barrel in 300 Win Mag?
Figure roughly 25 to 35 fps per inch compared to a 24 inch tube, so around 100 to 140 fps depending on the load. For hunting inside 400 yards or so, game animals will never know the difference. The handling you gain in tight cover and with a suppressor attached is well worth the trade for most hunters.
Does the Cascade SR come with a scope rail, or do I need to buy bases?
This model ships with a 0 MOA Picatinny rail on the receiver, so all you need are rings and your scope of choice. The Cascade action also gives generous scope clearance thanks to its 70 degree bolt throw, so larger eyepieces clear the bolt handle without trouble.
Is 300 Win Mag in the Cascade SR a good elk rifle?
Absolutely. The 300 Win Mag has been a go-to elk and big game cartridge for decades, with plenty of energy for elk, moose, and bear at practical hunting distances. The compact barrel and grippy Realtree Advantage stock make this version especially handy for timber hunts and dark timber setups where shots come quick.
