You start the thread and I'll chime in!Very Excellent, I did not know what the 458 JCE was, but looked it up and see you were here talking about it a couple of years ago...... I see where you tried to get a 458 B&M SS reamer but could not get it in Australia, so you did your own. Excellent, very unique and fun cartridge and capable of much bigger things than most would consider with only a casual look. Especially using Gen I and II bullets.
We should start a 458 JCE and 458 Super Short thread and compare notes..... I love mine, recently set it up so I could see with my left eye and shoot again.
Well done.

I assume you are using a WSM case as well, around 1.65 inches........ I run the 250 Socom Raptor from CEB at 2640 fps in my 16 inch guns at 55000 PSI, also using LilGun 53/Lilgun.I took my first Sambar with the "Juicer" in 2023 shooting 270gr Atomic29 bullets at 2600fps with a full case of Hodgden Li'l Gun (48gr). These produce a 1 1/2" group at 200 yards.
Yes, would be fun....... But unfortunately it is going to be first of the week or so before I can do so. I am headed out in a few minutes on a mission to Washington Dulles airport, no I am not on vacation, on a mission to retrieve rifles. Another Story all to its own. But yes, I think it would be fun to compare notes on the incredible little big bores............. ThanksYou start the thread and I'll chime in!
Excellent! But no rush - in 2 weeks my son and I fly to New Zealand south island to hunt Chamois, Himalayan Tahr and Red Deer. I'll be back at the beginning of May.I assume you are using a WSM case as well, around 1.65 inches........

Yes, cut a WSM case (any calibre) off at the shoulder, through the custom CH4D FLS die and trim to length. It's a fun little cartridge that punches way above its weight.I assume you are using a WSM case as well, around 1.65 inches........

Nice rifle! Have you taken Sambar with it? Water Buffalo?
Wow! What a great website! So much information about the different cartridges, it is going to take me some time read through all of it.I sent you a PM with more information concerning this.............
Nice! Look forward to your report. I didn’t realize how large sambar could get and a Water Buffalo hunt will be epic!Hey, thanks!
No, not yet... hoping to take a nice Sambar with it this year and hoping for a Water Buffalo hunt mid next year.
The only animal I have taken with it was a little Fallow I got while out with my young son.
It worked!

..with an accomplice in @Houston Bill, tells me about a 416 REM Mag that he’s glass bedded, upgraded the trigger, and added a mercury recoil reducer to the Winchester Model 70 with Leupold VX5 2-10 Firedot. So I decided who doesn’t want an extra 100 grains when going after the nasty dispositioned buffalo?I did. Lasted about 3 weeks. After I did some work to it another AH member needed a Buff gun for upcoming trip so sold it to him.
@Katy DarrenSome amazing guns in this thread. I’m a newbie Africa hunter, I’ve done two hunts the last two years and my third coming up later this year where I’ll pursue my first DG, Buffalo of course. I thought when I got my Ruger RSM 375 H&H with a Leupold VX6 2-12 Firedot that I was set for Buffalo. And I love this gun and have used it for Eland, Kudu, Sable and more. Then this guy

I just shot it for only the 3rd time today and it’s an accurate son of a gun, 6 of the 9 shots were touching and only the first cold barrel and two shots after scope adjustments were not.
As @mdwest says, enablers! Even @Bob Nelson 35Whelen pitched in while on his world tour when I first saw the gun at R&M asking me “what the….are you waiting for” in his Aussie accent. Maybe a curse word tossed in for good measure.
As much as the .416 Rigby is a delight to hunt with, for my mid year buffalo expedition here, I think the .500 Jeffery will get a run, complimented by the .400 Jeffery as the 'light rifle', making it an all Jeffery cartridge affair.

And I’m, maybe naively, optimistic that the long awaited .333 Jeffery will accompany @458JCE and I on our upcoming Chital and Fallow outing.
Most people know that I have strong feelings about the 375, all bad.I've not taken anything with them but I have a Ruger No1 in 458WM and a Browning X-Bolt in 375HH. My next African hunt will be for buffalo. Trying to figure out whether to bring either or, or both of them.
