"This is the most powerful sporting magazine rifle that has ever been placed on the market. It's a glorious weapon, and very easy and pleasant to handle and shoot. I used three of these rifles at different times, trying them out for their owners, and each time told myself that I simply must get one for myself. This is the only magazine rifle that has ever had that effect on me. I preferred it to the .505, but it's not easy to say why; I think the answer is to be found in the fatter fore-arm with which Jeffery fitted his weapons and which gave me a much better and more comfortable grip.
These were, I think, the most perfectly balanced magazine rifles I ever used. If I was having one built, however, I should certainly insist on a 22" barrel instead of the 24" that is normally fitted. The cartridge has an ample reserve of power to permit of this reduction in barrel length, whilst still leaving an adequate reserve. As with the 505, I was most pleasantly surprised at the lightness of the recoil, no normally constituted hunter would be worried by it in the slightest. I found it a most accurate cartridge and killed several elephant, rhino and buffalo with it, but cannot find any record of the numbers shot; all I can remember is, that no beast got away from me when I was using any one of these three 500's, I killed all I shot. It's an immensely powerful weapon.
My friend, C. Fletcher Jamieson, the Rhodesian professional, had Jeffery build him up one of these rifles to special order with a 26" barrel. He was a tall man of fine physique and owing to the way he held his rifles he reckoned he got better handling with a fairly long barrel. Since he had that weapon built, some ten or twelve years ago, he used it exclusively, and did a great deal of shooting with it. I'm not quite sure of the extent of his bag, but it cannot be far short of 300 elephant with this 500-bore Jeffery-Mauser, maybe more."
