Home Forums Hunting & Shooting Express Rifles and Big Bores Only My .500 Jeffery Problem

It has since buffed out though.😀

And some people think a 300 magnum kicks.

It's a Nock's form after the gunmaker Henry Nock

George, was that bruise from firing a Nock's volley gun ?
7 barrels of +50-cal ball and BP going off at once do feel a bit like Selous' 4-bore.
That can make the shooter spin like a weather cock in the wind, as the Brits might say.
Or like a weathervane.
Sort of like Nock's form versus knoxform.




Sort of like to the victor go the spoils:

RC, no, nothing as exotic as that. I noticed this after a range session for the plain old 458 Lott topped off by touching off a few 3 1/2” shot shells through one of those 6 lb H&R break-open 12’s. Those things should not have 3 1/2” chambers 😳😊.

Holy buttstock jumping out of the shoulder pocket Batman!!!!! LOL

Nice to see my photo's from 12 years ago still being used without credit, lol !

Aside from that ...

RCC just filed for Chapter 7 bankruptcy and won't be making brass for anyone anytime soon ...

I have 2.5 year old prepaid orders of brass for my "Wolverine" line on cartridges based on the 500 Jeffery case in 30 cal, 338, 8mm, 358, 375 & 416 ... with a 338 Lapua size rim diameter that won't see production & I'll never see my $cash$ again because Chapter 7 protects RCC from lawsuits for lost $$$

Thanks to Swamplord for use of his photos and,
sadly, news of RCC bankruptcy.
What little .500 Jeffery brass I have will be well cared for.
I'll get the rifle finished before 2023 passes.
Before 20 years passes.

I love my CZ 550 in 500 Jeffery. Has some issues with it feeding. Between Harlan at Triple River, Wayne at AHR and Kevin Weaver (Colorado Springs) we got it "sorted out" It feeds and functions flawlessly now, shoots sub MOA. I use Jamison Brass, CCI Magnum Rifle Primers, 103g H4895 and Barnes 570g TSX bullets. They chrono at 2300 fps. The load is straight out of Art Alphin's book "Any Shot You Want". Pictures (I also have a bruise picture caused by me not treating the rifle with enough respect the first time doing load development lol)

How did the rifle work out? Sorry haven't been on this forum in awhile. I have a CZ 550 in 500 Jeffery, love the gun!

OK. I'll get it done before the year is up.
Won't let it go longer than one score years.
I have been fiddling with 3 other rifles in the queue.
I 'll get to scraping a barrel channel tomorrow.

Interesting topic which made me review my PMs from Oct 2010 with a German friend about creating a 0.510” 505 Gibbs which would fit in an H&H length action (COAL 3.6”) DGR.

Didn’t make up a rifle for it but originally considered either a CZ Magnum or Ruger RSM, with a preference for the latter because of the feasibility of reboring a 416 Rigby (heavy barrel) or 458 Lott to .500”/.510”. I made up several dummies with Barnes 570 gn 0.509” monolithic solids. Looking back now, a Win M-70 long action, restocked for a larger magazine assembly which would allow at least 3 cartridges in the box, would better fulfill the original intent - fitting the modified 510/505 Nu Gibbs in a standard LA easily available DGR.

Altering the case to fit the COAL with that bullet required shortening the neck, but the Gibbs case retains at least the capacity of the 500 Jeffery case, so that cartridge’s MV should be achievable.

The main issue for this project is magazine capacity in the RSM or Win M-70 LA, which would favor the CZ Magnum route, but would negate the original intent. I still have the dummy cartridges and will post pics if I can figure out how. May need to revive the project later in the year. Too many irons in the fire currently.

Ditto irons in the fire.
Main problem with the Gibbs rim diameter
is the bolt diameter, magazine capacity is less a factor.
Even the CZ 550 Mag barely makes it on the bolt face.
It is a mere 0.700", same as Ruger RSM and most others.
Granite Mountain is better at 0.750" bolt diameter.
The defunct MRC M1999 PH is 0.800" in diameter, II RC.
And it has a drop box with inside mag box length of 4.02"
IIRC.
That would make a good .505 Gibbs wildcat.
That is what my .408 Chey-Tac "Sporter" is built on, a 10-pounder.
I need to get a muzzle brake on that for my old age.
Wouldn't want to tip over my wheel chair when the wheels are locked.

I am back to 3#6oz laminated stock
plus 7#9oz barreled action
for my .500 Jeffery-Procrastination,
11 pounds of comfort,
and a muzzle brake.
.500 Jeopardy.

Well i have Nosler 500 Jeffery brass I just bought, 100 pieces for $400. If you want 50 I can sell them to you for $4 each. I too like the Jamison brass but hard to find thse days. I have a lovely CZ 550 in 500 Jeffery. It will shoot one ragged hole groups at 100 yards when I do my part. Love the rifle. If i knew how to post pictures from Imgur to this board I would.

I guess I can share a boob picture too, my first time out with my 500 Jeffery, shooting in T-Shirt from the bench 570g TSX loads (6 rounds each) started out at 2150 fps last load 2510 fps. Ow ow ow! I've learned better, now it's my favorite rifle to shoot.

You’re a better man than I. A 500 grain bullet at 2350 fps from a 450 Rigby Rimless Magnum in a Ruger RSM is my limit so far.

I admire your courage and determination. Kudos!!!

I'm in the same boat with my 500 Jeffery project that has been on the backburner for about 20 years. I talked to Jack Huntington about finishing it up for me.

I didn't realize the brass issue is so dire, I have about 45 cases and would like to get another 50 before committing to investing in finishing it.
