Pillager, – Magnum Research, Inc, maker of the world renowned Desert Eagle pistol and leader in innovative firearms design and manufacturing, is proud to introduce the .500 Linebaugh BFR.

Magnum Research is pleased to bring another quality option to big bore revolver fans. The .500 Linebaugh was created in 1986 by John Linebaugh and is the largest production handgun caliber. What better pairing for Magnum Research’s “Biggest Finest Revolver” than the biggest handgun caliber? While a few companies offer the .500 Linebaugh as a full custom piece, Magnum Research is the only one to offer this caliber in a production revolver. The .500 Linebaugh has a bullet diameter of .510″ as compared to only .500″ for other .50 caliber rounds, excluding the .50 BMG.

Magnum Research’s BFR (Biggest Finest Revolver) is truly the biggest, finest revolver on the market today. Entirely manufactured in the US and like the legendary Desert Eagle pistol it is designed as a magnum from the ground up. The BFR is all stainless and has a precision grade barrel that delivers unmatched accuracy with lead or jacketed bullets. The BFR is the most powerful production single action gun made.

Max Prasac, an outdoor writer, author and big-game handgun hunter, recently had the opportunity to test a prototype. “Up until now, the .500 Linebaugh was a custom proposition only, costing thousands of dollars and long wait times,” says Prasac. “Now you can have one at a fraction of the price of a high-end custom, that will scratch your .50 caliber itch. I had the pleasure of testing the first prototype, and as I have come to expect from Magnum Research, it failed to disappoint. Leave it to Magnum Research to give big-bore revolver lovers exactly what they want!”

The .500 Linebaugh BFR is available in four configurations. The standard model with a 7.5 inch barrel (BFR500LB7) or 5.5 inch barrel (BFR500LB5) has an MSRP of $1399, and the standard model featuring Bisley grips with a 7.5 inch barrel (BFR500LB7B) or a 5.5 inch barrel (BFR500LB5B) has an MSRP of $1482. Contact your local firearms dealer to purchase today.

Rock, you are correct, sir!

Wild Bill

How does this compare to the 500 s&w?

The Revelator

@ Wild Bill The Smith is a longer round with more room for powder, but takes a longer cylinder. It is 1.625 inches for brass length, and 2.3 overall loaded. Has more power, but requires a stretched frame and a lot more weight/size. Might be a factor for some folks. The Linebaugh is shorter and fits in a wider variety of revolvers via conversions. It was made from .348 Winchester brass(essentially 50-110WCF) and cut down to 1.4 inches with an overall loaded length of 1.75 inches. The Linebaugh’s true beauty however is that it can be built on smaller revolvers… Read more »


The 500 Linebaugh has a cartridge diameter of .510 inches as compared with .500 inches for 500 Smith and Wesson, 500 JRH (which uses a shortened 500 S&W case) and the 500 Wyoming Express which uses a belted case for head spacing. If I understand correctly, all but the 500 Linebaugh are .50 inch diameter, The 500 S&W has a much longer cartridge case and the one that i owned in a short barrel was a very robust and great gun and closing the action was as solid as closing a bank safe. The recoil from the short barrel S&W… Read more »


I would bet that the BFR isn’t or wasn’t meant to stand for Biggest Finest Revolver…. I would put my money on Big F-ing Revolver !
