Description
The Grizzly Ammo GC357M8 brings straightforward .357 Magnum performance in a proven package. Built around a 158-grain round nose flat point bullet, this load represents what made the .357 Magnum a go-to choice for so many shooters. At 1000 fps and 351 ft-lbs of muzzle energy, you get solid ballistics without excessive recoil, making it manageable in various revolver platforms.
Grizzly manufactures this ammo right here in the USA, specifically in Rainier, Oregon. Each round is loaded to strict specifications using clean-burning powder and reloadable brass cases with non-corrosive primers. The round nose flat point design feeds reliably and cycles smoothly through revolvers and lever-action rifles alike. It's the kind of ammunition that works without drama, shot after shot.
Flat Point Design for Reliable Performance
The 158-grain flat point bullet is a workhorse configuration. This profile excels at feeding smoothly through most revolver actions, and the flat nose doesn't require the precision feeding that some other bullet styles demand. You get consistent chambering and reliable extraction, which matters when you're putting rounds downrange at the range or counting on your gun to work when it matters.
Versatile Platform for Any Purpose
Whether you're practicing at the range, zeroing in on targets, or just putting rounds through your revolver to stay sharp, this 158-grain load handles it all without flinching. The ballistics are straightforward and proven. You know what to expect, and Grizzly delivers consistency round to round. At 50 rounds per box, you get a solid block of ammunition to build a shooting session around.

Frequently Asked Questions
Can I use this Grizzly .357 Magnum ammo in a lever-action rifle?
Yes. The 158-grain round nose flat point design cycles reliably through both revolvers and lever-action rifles. The flat point profile feeds smoothly in tubular magazine fed rifles without the feeding issues you might get with some other bullet styles. Just verify your rifle is chambered for .357 Magnum before loading.
Will the GC357M8 work in my .357 Magnum revolver if I also shoot .38 Special?
Absolutely. .357 Magnum revolvers are designed to safely handle both cartridges. The .357 Magnum is simply a longer case loaded to higher pressure. If you want to alternate between the two for practice or to manage recoil, you can switch rounds without any issues. Just make sure your specific revolver is chambered for .357 Magnum.
Is this ammo reloadable?
Yes. Grizzly loads the GC357M8 into reloadable brass cases with Boxer primers, so once you shoot these rounds, you can reload the brass. The clean-burning powder leaves minimal fouling in your gun, which makes brass cleaning easier between reloading cycles.
What makes the round nose flat point better than other bullet styles?
The flat point profile was designed to feed reliably and cycle smoothly through the action, especially in lever guns. It produces a wider wound channel than a traditional round nose while feeding more dependably than a hollow point in some firearms. The flat meplat (face) also helps with energy transfer. For general-purpose shooting and target work, it's a solid, proven design.
