PRODUCT REVIEW

The 600 Nitro Express is the one of the largest of the Nitro Express rounds ever developed, second only to the .700 Holland & Holland Nitro Express. Originally meant for big-game hunting, its a round so powerful, it dents common handgun steel targets. As such, someone decided to build a handgun for it.

 

600 Nitro Express

 

The 600 nitro express revolver, along with the .577 Nitro Express, was a specialist backup weapon for professional elephant hunters. Too heavy to be carried all day and used effectively, it was usually carried by a gun bearer. It was used when in thick cover and when an effective shot at the heart and lungs was not possible.

When someone has to wear a helmet to fire the revolver, I think the loading is just a wee bit too hot. But, equipped with gloves, helmet and a huge muzzle brake, a dare-devil goes against all better judgement and pulls the trigger.

Design

The 6600 nitro express revolver is a slightly tapered walled, rimmed, centerfire rifle cartridge designed for use in single-shot and double rifles.[4]

The cartridge fires a .620 in (15.7 mm) diameter, 900 gr (58 g) projectile with three powder loadings: the standard being 100 gr (6.5 g) of cordite at a muzzle velocity of 1,850 ft/s (560 m/s); a 110 gr (7.1 g) loading which generates a muzzle velocity of 1,950 ft/s (590 m/s); and a 120 gr (7.8 g) loading which generates a muzzle velocity of 2,050 ft/s (620 m/s).

Because of the recoil forces generated by this cartridge, rifles chambered in it typically weigh up to 16 lb

History Of 600 Nitro Express

The .600 Nitro Express was developed by London gunmakers W.J. Jeffery & Co. Sources vary about the date of its introduction, although it would seem in 1900 the first .600 Nitro Express rifle was produced by W.J. Jeffery & Co, a 15 lb (6.8 kg) double barrelled hammer rifle. Jefferys produced around seventy rifles in .600 Nitro Express in four actions, double barrelled hammer break-open, single barrelled break-open, falling block and double barrelled break-open with and without ejectors.

Until the introduction of the .700 Nitro Express in 1988, the .600 Nitro Express was the most powerful commercially available hunting rifle cartridge in the world. Aside from W.J. Jeffery & Co, several gunmakers have and continue to offer rifles chambering this .600 Nitro Express, although in 2009 it was estimated by Holland & Holland that only around one hundred .600 Nitro Express rifles had ever been produced to that time.
