Ladies and Gentlemen,

See the link below, paying special attention to the last two sentences in the description. I thought some of you might enjoy the honesty.

Terry - yep, that about sums it up nicely - KMule......... ps Lorraine says howdy

T.Carr--KMule--This over-under would work perfect rechamber for my cartridge.Loaded at about
40,000 psi you'd have 2500 fps with 500 gr.Ed.

God bless the people who still say what they think these days!

I have never said that you'd get a "deal" on a rifle from George Caswell at Champlin Firearms. You will however know exactly what condition the rifle is in and what George thinks about it!

We band of brothers!

crap!
I was thinking it would be nice to own a double in 458lott someday. As I enjoy shooting my #1 and am setup to reload that round now.
Guess my choice in calb isnt so great for a double?
Nice looking rifle for an ou.

Ed,

What is your cartridge? 500 grain, 2500 fps @ 40k.

Thanks,
Roger QSL

Roger,

If you search on Ed's member number you will find his response in the thread on comparing cases from different sources where he uses his experiences with his extra long case on the .375 H&H head size.

I don't know how he does his pressure measuring though.

Roger-it is called 458 Hubel Express.It is discussed below in thread about Horneber brass.
Here is picture of them next to 458Win.It is 3.45 in long.perfect to rechamber single shots and break open actions, where length isn't problem.



We are going to get a run of brass made.Have tentative requests for 400 already in 4 days.The first set of tooling will do 20-25000 cases.If
we get the numbers up to use this run up,we will
have arrived as they say.And we will get more made.Ed Hubel.

Ed,

Quite a round. Have you chambered any guns for the round yet. Keep us posted under a new thread at this site.

Your belt is a little larger than HH. Why?

Thanks,

Roger QSL

Roger-I have chambered two , a Ruger 77 that I had
as a 458 Win(rechamber actually). And a P-14
Enfield with a long barrel..Have shot about 900 rounds through the
original 24 in barrel on Ruger,Then put on a
30 in barrel and shot a thousand.All shooting was load testing over a two year period.As for the base size I just extended the design of the 458Win
backwards, as that cartridge had the right taper but not enough capacity.By the term right taper I
mean it will take 55k loads without sticking and
with a straight taper using moderate loads
(40-45K) it can be reloaded 50 times.I built a 3 in cartridge at first but still didn't get velocity that I wanted with long life brass.About
2 hundred rounds of 3 in tested before I lenghtened it out.Ed.

Ed,

I take from your last post that the Ruger 77 is long enough to handle this long case. How is the cyle of the action with this size cartridge with both loaded and empty cases?
How are you coming up with pressure numbers?
What kind of loads,(powder and bullets) are you using? What's your chronograph showing?

Yea, I know, a lot of questions. Just really interested in your project. Have been thinking about doing something with the 400HH, but will just wait and see what develops at your end.

Again, thanks for the info.

Roger-The Ruger was used as a single shot, and then I had to narrow up back bridge to make port long enough.I made a different bolt stop.On the Enfield it is single also,for now , but if I want to,I can change sear spring arrangement,and it is long enough to open up to get magazine in.I used
a chronograph, no guessing.With hard base brass
(which is what Hornebers is)500 gr over 2800fps,
450 gr over 3100fps,400 gr over 3300fps, and
350 gr over 3500 fps.The hard base brass I had was
soft on the sides and was only good for 6-8 reloads.The softer base brass that I have left, gave about 100-150fps less, but the sides were uniform and that can be reloaded 50 times with moderate loads.Hornebers brass will be harder and uniform so it will reload many times.For pressure I used Homer's pressure sliderule to
figure pressures, aswell as mike cartridges at
the belt and head.The two best powders for 500 gr
for example, had starting velocities of 2500 fps.They were WIN760 and H414 , loaded at 90%
case capacity.they both gave 2800 fps with compressed loads, and this was with soft headed brass.The starting loads didn't have to have much resizing,And the full loads didn't stick at all with these two powders.Ed.

Ed,

Very impressive numbers. Especially, the 500 at 2800. If your starting the 500 grain load at 2500, then it seems to me the pressure sould be very low. This could make for a very wonderful DG load for doubles.

If the Ruger can be made to handle this round, then it could catch on.

Would you do us a favor, and start another thread here at AR, with it's own heading. I'm not sure the balance of the hard core here are catching this data. I'm sure a lot of curious double shooters will be very interested.

Where did you get the reamer for this round?

If you don't mind, would you send me, via E-mail anymore results of your load development. MY "E" is located in my personal's.

Must be a real thumper at the bench.

Thanks,

Roger QSL
