Short fore-ends are not uncommon on large calibre Brit doubles, as the barrels are already quite hand-filling and extra wood is simply an encumberance. After all, the fore-end's only job is to prevent the barrel-group falling off when the gun is opened! ...and to house the ejectors if fitted.

If anything, the barrels are a bit long for a Jeffery boxlock, many were 24 inches.

I imagine you'd know, Nigel, but compared with the NE version it would have to be better unless the extra mass of the NE rifle nullifies all distinction. Using Nitro for black loads would drop the ejecta load by about 100 grains, too. While not experienced in such big calibres myself, 650 grains at 1650fps from a 12-pound rifle sounds like a gentler proposition than 500 grains at 2050-odd from an eight-pound 458.

Cheers

Recoil is heavy, far more than I had expected and more than the .458s and similar I have used, and I have had many down to eight pounds, including Ruger #1s in .500 NE # 1/4" and all the big .45s including .460 Wby at nine pounds. I would compare this double recoil to that of the nine pound .500 with 650 casts at 2100. It could be a bit lighter, I have not shot it since last fall. I will have to get these 650s over the chronograph the first chance I get.
I will try to get some pictures posted tomorrow.

@Yukon577
If you can't wait, the book "Shooting the British double rifle" is in stock at a Belgian bookshop (52€ I believe). You can mail them at mail@hataritimes.com if you want more info.

As explained above, Yukon, I am a babe in the woods in these matters but the load you mentioned shooting sounded to me like the full nitro-express version, meant for a rifle two or three pounds heavier. The nitro-for-black load would be easier on the rifle and your shoulder.

I agree - it did sound like the full Nitro load now I think of it.

The load came from the book I mentioned. Does anyone have the book to look this up and see what it says regarding this load? I simply got the load written down, I didn't have a chance to read all it said about it.
As mentioned, my gun is marked 650 grain bullet 6 1/2 drams #6 powder. I would like to use the load that gives the same speeds as that load. With my limited shooting of about 12 rounds with the load from the book, my rifle did shoot right to the standing blade at 50 Meters. I would be very pleased if it shot as well with a slightly lighter load as it would be a lot more pleasant to shoot long term.
Another thing I should mention is that I have not shot the 650 grain jacketed bullets yet, this load was with a 650 grain round nosed cast bullet.

Yukon

In regards to "would be very pleased if it shot as well with a slightly lighter load as it would be a lot more pleasant to shoot long term."

once you work out the load that works in the rifle, apply the 75% rule and see if you can get it to shoot.

That way you will end up with a lighter load.

Please explain the 75% rule to me. Do I just put in 75% of the powder charge or do I seek a load that gived 75% of the velocity with the same bullet, 75% of bullet weight? I have not heard of this before.

yukon

the 75% rule is same powder but a 25% lighter head(300 grns. instead of 400 grns. in 450/400 for example). that often shoots to the sights.

best regards

peter

Thanks Peter.

Another good example is is the 500 Nitro, 440gn bullet instead of the 570gn bullet.

Thanks guys, I get it now. I have some moulds with bullets in the 465 to 500 grain range already too, so this might work out well.
Are there jacketed bullets in this weight available? I have used cast bullets of this weight a fair bit in my Sniders but have never even looked for a jacketed bullet for that purpose.
I also have a .577 NE 3" project gun under construction. It is a heavy barrel single shot on a Riedl falling block action. The action is massive and has never been made up into a rifle so is in new condition though it was made in the early 70s. The barrel I have fitted is long and heavy to give it some weight. It has only been test fired to this point. It lost priority once I got the Jeffery double.
Regarding the 75% rule, the first ammo I loaded for the .577 double was with a bullet of about 485 grains. It was with a lighter powder charge though. It did shoot well and consistent, but it shot a lot higher than the point of aim at 50 Meters. I wonder if I go back to the heavy charge with these lighter bullets, if they will come down to my point of aim. It would be worth a try and I am sure they would be more pleasant to shoot than the heavies.

Guys,
I got some pictures over the weekend, I just have to figure out how to post them now.
A couple of hours ago I was looking at a nice big wood bison down the sights of the Jeffery. He moved off before I got a shot and never did get a chace to shoot, but it was exciting and I almost got to see what the big .577 would do on one. Next time he won't be so lucky.

That would be my ten year old son!

He doesn't own a double rifle yet, but he did get a lovely pre war Meffert single shot in .22 Hornet this year. Just waiting for the gophers to come up and we will both hit the field with our new(old) Hornets. Looking forward to that quality time.

Does anyone know how to go about requesting the records for my W.J.Jeffery double rifle? I do know that the current Jeffery company does not have them. Any info would be appreciated.
Thanks,
Yukon
