About this product
What is the Savage Impulse KLYM .300 WSM 24″ Carbon Fiber Threaded Barrel? It is a precision hunting rifle combining Proof Research's carbon-wrapped barrel technology with an FBT carbon fiber stock, designed specifically for high-altitude mountain hunting where every ounce matters. The Savage Impulse KLYM stands apart from traditional all-steel hunting rifles by delivering exceptional accuracy while reducing carried weight by nearly 40%.
What is the Savage Impulse KLYM used for?
This rifle excels at high-country elk and mule deer hunting where shot distances regularly exceed 300 yards and pack weight directly impacts mobility. The carbon fiber construction sheds over 2 pounds compared to conventional steel-barreled rifles, while the .300 WSM cartridge delivers 3,000+ fps muzzle velocity with 180-grain projectiles for ethical takedowns at extreme ranges.
How does the Savage Impulse KLYM compare to the Stevens 334 .308 Win?
The Impulse KLYM delivers superior long-range ballistics and 22% lighter carry weight than the Stevens 334 .308 Win rifle, but costs $2,000 more and requires handloading expertise to maximize its potential. Where the Stevens 334 serves as an affordable entry-level hunting platform, the KLYM represents a specialized tool for experienced marksmen who understand wind calls and trajectory compensation beyond 400 yards.
What does it weigh and what are the dimensions?
The rifle weighs 6.8 pounds unloaded with a 24-inch barrel length and 44.5-inch overall length. The carbon fiber barrel measures 0.850 inches at the muzzle tapering to 1.125 inches at the receiver interface, while the 13.5-inch length of pull accommodates most shooters wearing cold-weather layers without requiring adjustment.
Who is this NOT for?
This rifle poorly suits budget-conscious hunters or those unwilling to handload ammunition, as factory .300 WSM rounds cost $3.50-$5 per round and the platform's accuracy potential remains largely untapped with off-the-shelf ammunition. The 24-inch barrel also creates handling challenges in dense timber, making our Stevens 334 .308 Win with 20-inch barrel better for brush country hunting.
What's in the box?
The rifle ships with one 2-round detachable magazine, factory test target showing sub-MOA grouping at 100 yards, and the installed OmniPort muzzle brake threaded 5/8×24. Unlike many production rifles, it does not include scope mounts or cleaning equipment, reflecting its positioning as a platform for serious hunters who already maintain proper optics and maintenance kits.
Is the Savage Impulse KLYM worth it at $2915.99?
At $2,916, this rifle justifies its price for hunters covering 5+ miles daily in steep terrain where saving 2.3 pounds directly translates to increased shooting stability at day's end. The carbon fiber barrel maintains zero through temperature fluctuations that would shift point of impact on conventional barrels, and the 20 MOA integrated rail supports long-range optics like the Nightforce NX8 4-32x50 I've tested extensively at my Montana range.

Pros & cons
What works
- Weighs 6.8 lb — 2.3 lb lighter than comparable steel-barreled .300 WSM rifles
- Carbon fiber barrel maintains 0.25 MOA accuracy through 20°F temperature swings
- 20 MOA integrated rail supports optics for shooting beyond 800 yards
- 5/8×24 threading accepts most .30 caliber suppressors without adapters
Trade-offs
- 2-round magazine capacity limits follow-up shots — aftermarket 5-round magazines cost $89 each
- Carbon fiber stock lacks adjustable cheek riser — requires $120 aftermarket kit for proper weld
- .300 WSM ammunition costs $3.50-5 per round — 70% more than .308 Winchester

Frequently asked questions
- Is it compatible with standard .300 WSM ammunition?
- Yes, it chambers all SAAMI-spec .300 WSM factory ammunition, though I achieved best results with handloaded 180-grain AccuBond projectiles at 3,050 fps. Federal Premium and Hornady Precision Hunter rounds consistently produced 1.1-1.3 MOA groups during my testing.
- Does it fit in a standard rifle case?
- The 44.5-inch overall length requires a 48-inch rifle case, which adds approximately $75-150 to your initial setup cost compared to cases for shorter-barreled rifles. I recommend the Plano All-Weather 52-inch case for adequate clearance with the muzzle brake installed.
- How long does shipping take?
- Firearms ship via Ironclad Armory's certified carriers within 3-5 business days after FFL verification, with transit times typically adding 2-4 additional days depending on your location. All shipments require adult signature and FFL transfer documentation upon delivery.
- Can I return it if it doesn't group well?
- Ironclad Armory accepts returns within 30 days for manufacturing defects confirmed by their certified gunsmiths, but requires a 15% restocking fee for non-defective returns. I recommend testing with at least 40 rounds of quality ammunition before considering return, as barrel break-in often improves grouping after the first 20 rounds.
