Description
The BFR stands for Biggest Finest Revolver, and Magnum Research isn't just being cute about it. This is a large-frame, single-action wheelgun chambered in .45-70 Government, a rifle cartridge that has been putting down big animals since 1873. Fitting that round into a revolver requires a long cylinder, a beefy frame, and tight tolerances throughout, and that's exactly what you get here. The frame, cylinder, and barrel are all brushed stainless steel, built to handle the field abuse that comes with serious hunting and backcountry carry.
What Makes the BFR .45-70 Shoot So Well
Magnum Research runs each barrel through a precision cut-rifling process, followed by hand lapping and a recessed crown. Barrel-to-cylinder alignment is held to under .002" concentricity and the cylinder gap stays under .005", which are tolerances you'd expect from a target pistol, not a hunting revolver. Each BFR is hand polished, hand fit, and hand assembled before it leaves the factory. That attention to detail at the manufacturing level is a big reason the 7.5" barrel on this gun is widely regarded as one of the sweet spots in the BFR lineup for both accuracy and velocity.
The sights are a fixed black front paired with an adjustable rear, and the frame is factory drilled and tapped to accept the included Weaver-style scope mount. That's a nice setup for anyone who wants to run a red dot or a low-power scope for longer handgun hunting shots. The transfer bar safety means you can carry this gun with all five rounds loaded without worrying about an accidental discharge if the hammer gets bumped.
The .45-70 in a Revolver: Recoil, Ammo, and Real-World Use
One thing that surprises people about the .45-70 in this platform is the recoil story. The cartridge operates at much lower chamber pressure than something like .454 Casull, and the BFR's weight, around 4.3 lbs unloaded, helps tame what push there is. It's not a soft shooter, but it's manageable with practice, especially with lever-gun pressure loads. The black rubber Hogue-style grip included from the factory gives you something to hold onto when things get loud. The .45-70 is also widely available, reloadable, and handles everything from cast lead plinking loads to hot hunting ammunition designed specifically for handgun-length barrels. If you're after deer, hogs, elk, or even dangerous game in a sidearm format, the BFR in this chambering is a legitimate tool, not a novelty.

Frequently Asked Questions
What kind of ammo can I shoot through the Magnum Research BFR in .45-70?
The BFR .45-70 is designed to run standard lever-action rifle loads, which are the most widely available and best suited to this platform. Magnum Research specifically recommends lever-gun pressure loads rather than the hottest handloads or modern high-pressure rifle loads. The cut-rifled barrel handles both lead and jacketed bullets well, and there's a solid selection of factory hunting ammunition made specifically for big-bore handguns in this caliber.
Is the Magnum Research BFR .45-70 safe to carry with all five rounds loaded?
Yes. The BFR uses a transfer bar safety system, which blocks the hammer from reaching the firing pin unless the trigger is actively pulled. This allows for safe full-cylinder carry without the traditional single-action concern of carrying on an empty chamber. It's a modern safety feature that makes the BFR more practical for field carry.
How bad is the recoil on a .45-70 revolver?
It's stout, but more manageable than most people expect. The .45-70 operates at relatively low chamber pressure compared to cartridges like .454 Casull, and the BFR's solid stainless construction and approximately 4.3-lb frame weight absorb a good deal of the push. With standard lever-gun loads and the included rubber grips, most experienced revolver shooters find it very workable. That said, it's not a cartridge you'd want to spend two hours plinking with, and you should always work up to it.
Does the BFR .45-70 come ready to mount a scope or optic?
Yes, and that's one of the more useful features on this gun. The frame is factory drilled and tapped, and Magnum Research includes a Weaver-style scope mount in the box. Any standard Weaver-compatible rings will work, so you can run a compact scope, red dot, or reflex sight without any extra machining or gunsmithing needed.
Is the Magnum Research BFR a good choice for handgun hunting?
The 7.5" barrel is widely considered one of the best configurations in the BFR lineup for hunting applications, offering a solid balance of velocity, barrel time, and overall portability. The .45-70 cartridge delivers serious terminal performance on large and dangerous game, and the BFR's precision-grade barrel and tight manufacturing tolerances make it accurate enough for ethical shots in the field. If you're serious about handgun hunting, this is a purpose-built tool and not a gimmick.
How is the BFR built compared to other production revolvers?
Magnum Research builds the BFR to tight standards that go well beyond most production revolvers. Each one is hand polished, hand fit, and hand assembled, and the barrels are precision cut-rifled, hand lapped, and recessed crowned. Barrel-to-cylinder alignment is held to under .002" concentricity with a cylinder gap under .005". Frames, grip frames, and cylinders are all machined on CNC equipment using a proprietary process developed specifically for the BFR platform.
