Description
Buffalo Bore built the Heavy .35 Remington to take this classic cartridge beyond its standard specifications, offering hunters and rifle enthusiasts serious velocity and knockdown power in a lever-action friendly package. Using a 220-grain Speer semi-jacketed flat point projectile, this load achieves 2200 fps and 2364 ft-lbs of muzzle energy from an 18.5-inch barrel. That's the kind of horsepower you're looking for when you need deep penetration and reliable terminal expansion on game ranging from whitetail to black bear.
Semi-Jacketed Flat Point Design
The flat nose profile is critical for levergun reliability in tubular magazines, but the semi-jacketed construction offers something standard softpoints can't quite match. The exposed lead tip combines controlled expansion with serious penetration potential. Field reports consistently highlight impressive exit wounds and the ability to drill completely through large game. The energy transfer is dramatic when the bullet makes the impact, and that translates to quick, clean results.
Loaded to Full Potential
Buffalo Bore loads these to maximum SAAMI specifications, which means they pack considerably more punch than standard factory offerings. That extra velocity matters in brush, timber, and at reasonable hunting distances where the .35 Rem typically works best. Accuracy testing shows this load delivers tight grouping in modern Marlin 336 rifles, with multiple reports of sub-2-inch groups at 100 yards. The ammunition is new production, boxer-primed, and loaded in reloadable brass cases.
Rifle Compatibility and Performance
This ammunition is specifically designed for Marlin lever actions, Thompson Center single shots, and modern bolt-action rifles chambered in .35 Remington. Buffalo Bore includes clear warnings on packaging about which rifles are safe for this load, and you'll want to ensure your rifle is in sound condition before firing these warmer rounds. The ballistics are printed actual velocities from real rifles, not marketing numbers. If you're hunting medium to large game inside 150 yards and want to eliminate the limitations that standard .35 Rem loads impose, this is the ammunition that lets that rifle shoot significantly above its weight.

Frequently Asked Questions
What rifles is this Buffalo Bore .35 Rem ammunition safe to use in?
This ammunition is designed for modern Marlin lever-action rifles, Thompson Center Encore single shots, and modern bolt-action rifles chambered in .35 Remington. It is loaded to maximum SAAMI specifications and should not be fired in older rifles, semi-automatic models like the vintage Remington Model 8, or firearms in poor condition. Make sure your rifle is in sound working order before using these heavier loads.
How does the 220-grain load compare to standard factory .35 Remington ammo?
Buffalo Bore's 220-grain load delivers noticeably higher velocity and energy than standard factory offerings. At 2200 fps and 2364 ft-lbs of energy, it provides significantly better penetration and terminal performance while remaining suitable for hunting medium to large game. The heavier bullet combined with increased velocity creates impressive exit wounds and more reliable expansion compared to lighter standard loads.
Will this ammunition cycle reliably in my lever-action magazine?
Yes, the semi-jacketed flat point design is specifically engineered for feeding reliably in tubular magazines like those found in Marlin 336 rifles. The flat nose profile prevents feeding issues and is safe for magazine stacking. This ammunition should cycle smoothly through your levergun without any feed problems.
Is this ammunition reloadable?
Yes, Buffalo Bore uses new production, boxer-primed brass cases that are reloadable. Many reloaders appreciate being able to reload these cases for custom handloads, though the warm pressures and velocities Buffalo Bore achieves would require careful attention to published reloading data for the .35 Remington cartridge.
