Description
The Magnum Research BFR Rolling Thunder is a big-frame, single-action revolver chambered in .45-70 Government and built for serious handgun hunters. This model (UPC 761226090489) has a 3-inch barrel, a 5-shot long cylinder and a brushed stainless steel finish.

Magnum Research BFR Rolling Thunder Overview
Magnum Research calls the BFR the biggest, finest revolver on the market, and it backs that up. Like the Desert Eagle, it is manufactured entirely in the United States and designed as a magnum from the ground up. It is all stainless steel, with a precision-grade barrel that delivers outstanding accuracy with lead or jacketed bullets, and it is one of the most powerful production single-action handguns made. The Rolling Thunder version packs the BFR action into a short 3-inch barrel with black grips, creating a compact powerhouse that is drilled and tapped for optics mounting.
Built for Handgun Hunting
Engineered for the hunt, the BFR can take everything from small game to the largest North American animals depending on chambering. The factory fixed front sight and adjustable rear sight are easy to zero, and the trigger breaks cleanly at about 4 to 5 pounds for precise shots at extended handgun ranges.

Big-Bore .45-70 Government Power
The .45-70 Government has been taking big game for nearly 150 years. Its heavy, large-diameter bullets hit with authority on bear, moose and bison, and modern loads extend its effective range. In a short-barreled revolver it makes a formidable backcountry defense gun in brown bear country.
Stainless Steel Construction
As a true stainless steel revolver, every major component resists corrosion, so it stands up to rain, snow and long days in the field. The brushed finish hides wear, and the massive frame and heavy barrel help absorb recoil from stout hunting loads.

Practice and Load Tips
Start with lighter loads to learn the single-action manual of arms and the sight picture, then work up to full-power hunting ammunition. Shoot from sitting, kneeling and supported field positions, and confirm your zero with the exact load you plan to hunt with. A good chest or hip holster makes carrying a revolver this size comfortable in the woods.
Safe Storage at Home
Whenever a handgun is not on your body, keep it locked in a quick-access safe or lockbox, especially if children live in or visit your home. Store ammunition separately when the gun is put away long term. A small biometric or keypad safe by the bed keeps a defensive pistol secure yet quickly reachable, and a cable lock is an inexpensive option for travel or range bags.
Choosing Ammunition
For practice, inexpensive full metal jacket loads let you shoot often without breaking the budget. For defense, choose a quality jacketed hollow point from a major maker and confirm it feeds reliably in your pistol by firing at least fifty rounds of it. Keep carry ammunition fresh by rotating it into practice every six months or so, and store spare ammunition in a cool, dry place.
Cleaning and Maintenance
Field stripping is quick and makes routine cleaning easy. Wipe carbon from the slide, barrel hood and breech face, run a few patches through the bore and put a drop of oil on the slide rails and barrel. Inspect the recoil spring and magazine springs periodically and replace them if they feel weak or the pistol starts to malfunction.

Before You Buy
This is a large, heavy revolver; expect a weight of several pounds and plan on a sturdy holster. Full-power hunting loads produce stout recoil, so practice with lighter loads first. A 3-inch barrel produces substantial muzzle blast and recoil with full-power .45-70 loads; use loads suitable for revolvers and wear hearing protection.
Who It Is For
The Magnum Research BFR Rolling Thunder is a great fit for backcountry hunters, guides and anglers in big bear country who want a compact, incredibly powerful revolver, and big-bore fans who want something truly unique.
