Buffalo Bore engineered the 36B20 as a dedicated hard cast load for hunters who take the .32 H&R Magnum to the field. The 130 grain hard cast bullet at 1,125 fps isn't flashy, but it gets the job done. With a Brinell hardness of 21-22, the bullet maintains its shape through impact and doesn't deform when hitting bone. That means penetration over expansion, and that's exactly what drives this design.
This load is engineered for the kind of penetration that matters in the field. It drives roughly three feet into flesh and bone, translating to performance that can cleanly harvest small to medium game. The hard cast construction resists leading and the cartridge comes loaded in quality brass that's reloadable for folks who want to stretch their ammunition budget even further.
Buffalo Bore publishes velocities from actual revolvers on the shelf, not tricked-out test barrels. That 1,125 fps figure comes from production guns people actually own. The flash-retarded powder keeps low-light vision intact if you ever need to shoot in dim conditions. Each box packs 20 rounds, and you get a straightforward, proven cartridge that works in any .32 H&R or .327 Federal firearm.
The combination of hard cast bullet design, controlled velocity, and careful manufacturing means this ammunition delivers consistent performance. It's the kind of load that makes a difference when you're out hunting and every shot needs to count. The .32 H&R Magnum gets more respect when it's loaded this way, and folks who use Buffalo Bore's 36B20 tend to keep coming back.
Yes, this +P rated ammunition is safe for all firearms chambered in .32 H&R Magnum and .327 Federal Magnum, as long as your gun is in normal working condition. The only exception is original H&R revolvers, which are long out of production. Always confirm your firearm can handle +P pressures before shooting.
Hard cast bullets maintain their shape and flat nose profile as they penetrate through tissue and bone, unlike soft lead bullets that deform on impact. This creates a consistent, sharp-edged wound channel and maximizes deep penetration, making the 130gr hard cast ideal for hunting applications where you need reliable, straightforward ballistics.
The 130 grain projectile delivers superior penetration and momentum compared to lighter 100 grain offerings, making it better suited for reaching vital zones on game animals. It also recoils moderately enough to shoot all day while packing enough power to get the job done in the field.
Yes, Buffalo Bore tests their ammunition in standard, over-the-counter revolvers rather than using artificially long test barrels. The published 1,125 fps represents what you'll actually get from production guns, not misleading lab figures that don't reflect real-world performance.
