Description
The .327 Federal Magnum hits a sweet spot that a lot of revolver shooters have been looking for. You get magnum-level performance without punishing recoil, plus this Buffalo Bore load is built to deliver. The 100-grain JHP moves at 1,450 fps from the factory test barrel and carries 467 foot-pounds of energy, making it genuinely capable for both range use and defensive work.
Buffalo Bore Heavy 327 Federal Design
This load came about because Buffalo Bore customers kept asking for it, and the company listened. You get a full-power cartridge with brass cases and Boxer primers that are reloadable, giving you options down the road. The 100-grain JHP uses symmetrical skiving around the hollow point cavity to promote reliable expansion while controlling penetration. That matters whether you're working targets or counting on this round for something more serious.
Flash-Suppressed Powder for Low-Light Performance
The real differentiator here is the flash-suppressed powder formulation. If you ever need to fire in dim conditions, you won't get blinded by your own muzzle flash. That means better follow-up accuracy and vision retention when it matters. It's a straightforward feature that shows Buffalo Bore thinks about the practical side of shooting.
Real-World Velocity Testing
Buffalo Bore publishes velocities from actual stock firearms, not extended laboratory barrels. That 1,450 fps rating comes from real revolvers you can actually use, so you know what to expect. That kind of transparency builds confidence in the load, especially when other manufacturers pump exaggerated numbers from unrealistic test setups.

Frequently Asked Questions
What firearms can I safely use with this 327 Federal Magnum load?
Buffalo Bore rates this ammunition for all-steel revolvers and standard pistols chambered in .327 Federal Magnum. The company does not recommend these loads for super-lightweight alloy revolvers, which can experience crimp jump under the recoil. If you're unsure about your specific firearm, check the manufacturer's specifications or contact a gunsmith.
How does the 100-grain JHP in this Buffalo Bore load compare to other 327 Federal options?
This 100-grain JHP sits in the mainstream of .327 Federal ammunition by weight and delivers solid velocity at 1,450 fps. The symmetrical skiving on the hollow point promotes reliable expansion, and the flash-suppressed powder gives you an advantage over standard loads in low-light scenarios. It's a capable all-around choice for both range work and defensive use.
Why does Buffalo Bore publish velocities from standard firearms instead of test barrels?
Buffalo Bore publishes velocities from actual stock revolvers to show what you'll realistically see when you shoot. Many ammunition makers use extended laboratory barrels that generate inflated velocity numbers. By testing from standard firearms, Buffalo Bore ensures you know exactly what to expect when you pull the trigger.
Can I reload the brass cases from this ammunition?
Yes, the cartridges come with reloadable brass cases and non-corrosive Boxer primers, giving you the flexibility to reload them after firing. This makes them practical for shooters who handload, which can help offset the cost over time if you shoot regularly.
