Frank,
Glad to hear ya! When you get the dies, it's once pass to form the body, POP the fireforming load, and trimm.
If you like, pull the trigger on em all!!! The 458 will perfectly clean up a 458 winmag chamber, and if the markx is feeding ...well, with it being a markx, and the back is a little narrow, it MIGHT need a few minutes of work to make it work,... and might not.
I gimme a call tomorrow, and we'll chat on it!!
Jimmy,
your arm healing up for all that ridiclous amount of brass forming work? Sure you are up to 15 mins for 100 piece of brass?

I think I can manage...I might need a Dr's note from Dr. Jeffe when my gun is ready though...they will be wondering where I went at work.

Frank MartinezGood concept on the Rum brass matching up.
I sort of have my heart set on my double rifle for anything that might need the .458.
Frank
Jeffe, I will be working late for a while but will call to talk it out.

Hi Jeff,
After looking at Paul's photos of the Ultra Mag case holding the .475 bullet the headspaceing shoulder looks almost non exsistent. I tried taking the 470 Mbogo up to .510 and ran into the same situation but not quite as fine. I thought it was unreliable at that point. What do you think of it. You may have to blow the case out some what to increase the shoulder dimension allowing you a larger headspace dimension. I haven't really looked at the case taper yet but keep it to .005 per inch for trliable extraction. The 416 sounds the most interesting to me. See you in a month.
Take good care,
Dave
Dave,
Here we are, at this time of year again.. though, dang it, you won't be here!
Funny how much changes in a year, with Rich doing a working (more or less) 500 mbogo and the 470 AR a nice working rifle.. and neither have headspace or shoulder set back issues... If you recall, I had the same concepts of it not working, but was assured by some folks it would be fine... So, in all honesty, the 470AR is the slickist feeding rifle I own... There has been zero headspace issues with ammo, and certainly none have setback the shoulder.
Wish you would were here to try it.!!

Idaho SharpshooterI do not...at least not to date Jeffe. BTW, the shop has an Obendorf Mauser action (less trigger) available...any thoughts? I think about $200 or thereabouts. Also has a couple others if you are interested...? Lastly, the guy with the M30 and 1917 stuff is uspposed to be by today. Will let you know if there is anything you might want.
regards,
Rich

boom stickwoo hoo! (homer voice)
could you magazine feed any bmg bullets from a converted 416 rigby or wby???
01 August 2007, 00:01
Paul HHmm, after two 458 lotts, I'm thinking I really need a 416 AR. I still have a couple of projects between now and then, but this thread has rekindled my need for something big, but not too big. I'm thinking 325 tsx @ 2700 should be about right for NA use.

jeffeossoPaul,
I haven't tried any of those.. but 350s at 2575 are a breeze... and 400s at 2400+ aren't hard to do...
besides, you need to make all three... your name is on them too!!

Paul HI have thought about a 470, as I've got several .475" molds. That said, I just don't get as much shooting in as I used to, and am gearing my guns towards stuff I can pick up and shoot while ignoring the recoil. The 458 Lott's taught me what I can handle when I'm shooting fairly frequently, as well as what I should avoid if I don't shoot frequently.
After having our dog wake us up early Sunday morning on our camping trip to alert us to a large black bear feeding on berries near camp, I can see the use of a light weight powerful iron sighted stopper. A 458 just has too much recoil in the weight I'd want, the 416 allows a fairly thin barrel, and with the lighter bullets is pretty controllable.
Hmm, maybe I just need a, gasp, 45-70 guide gun

Oh jeez! Boomer you quoted it! I accidently read his crap. You circumvented my ignore function.
The blowhard cannot quit fabricating about his hurt feelings over his fabrications. It is self perpetuating self-pity. He is wallowing in self-pity. What a self-centered boob.
The fact is he did an expedient, weak effort in using a .510 Wells without a belt, with a very weak shoulder, after jeffeoso and I announced plans to do the 500 Rigby, long and short as they are.
Jeffeoso's and my cartridge drawings predate, his expedient weakness, and unveiling of the "weak" beltless .510 Wells.
And many other wildcatters predate us all here. Gil Van Horn rings a bell, eh?
The Idaho Zephyr is a weak wind. The gentle, warm breeze from the west. Hot air.
If you promise not to quote him anymore, the air will be fresher.

Swap your guide gun for a Ruger MkII 7Rem mag. Then build your 470AR.
01 August 2007, 09:40
MacifejHey RIP!
You guys might consider drawing up some new cartridges which aren't based on any existing brass or cartridge and have them made with your own headstamp. Then you wouldn't have to suffer fools here on the AR forum. All mine are Copyrighted and Patented so there are PENALTIES for interlopers.
Just a hypothetirhetoricaliberistic thought!

Yep. Progress would be fun to watch.

I am sure the "Band of 45/70ers" allow alumni membership, especially while pursuing such a worthwhile diversion.

Thanks, Macifej, but I am just a poor little working stiff without the time or money for endeavors such as yours. This stuff is just for fun, by me.
.40-07 (.395 Tatanka) and .50-08 (500 Mbogo): At least one of them is distinctly original. I will have properly headstamped brass someday, even if I am the only one in the world in possession of it. That is cool too.
You have the "Seventy-Ought-Ten" sewn up.
If I ever venture into your territory it will be a "Sixty-Nought-Nine."

Paul HIf I stumbled into a Ruger 7mag I'd have to build myself a 416. That said, the guide gun as the appeal of something that works as is, I'd just need a good 400 gr WFN mold for it and I'd be set.
Simplicity has it's appeal.

Chris,
My thoughts on cast bullets in a rifle is peek performance is with muzzle velocity of 1800-2000 fps, assuming you can get consistant exits with bullets of that weight. With a 45-70 Marlin that would be 450-400 gr bullets. From what I've heard the 45-70 will penetrate fine with bullets of that weight on soft skinned game, including the great bears. So, I can't see the advantage of the heavy pile drivers, and perhaps they give up a bit of wound channel.
Can't believe I'm finally coming around to a cowboy gun, but they definately have their place.

LfalerJeffe, I think I asked this once before, but can't remember. Who is doing the chambering/work for converting a rifle to a 470 AR. I have a ruger and a mauser action looking for a home.

jeffe,
The AR series is a bloody good idea that's why people enquire. Add to that the fact that Winchester 458WinMag brass is just about made of "unobtainium" locally and the 458AR starts to look very nice indeed!!
I'm awaiting a reply from Manson on a reamer/headspace guages quote ... then we'll try getting the ball rolling on bringing the 458AR Down Under.

Cheers...

boom stickcome on con...go with the uber snooty exclusive 470...you got good woodleigh bullets there...
28 September 2007, 10:35
Conboomy,
Personally it's my prefered option as I can rechamber/rethread the Capstick barrel and shift it from a Rem700 to a Ruger MkII. Otherwise sourcing a 0.475" barrel is tough, and some suppliers of bits and pieces are reportedly not sending stuff to Australia due to some changes on your side of the pond. But we'll be exploring the option to import PacNor prechambered but unthreaded barrels as an alternative to buying the reamer. Also ... the "bigbore" handgun bans over here have severely limited projectile availability ... and the 470AR aint any good if you cant shoot pistol projectiles!! It would literally be a one bullet rifle. The 458AR atleast has the option of 300gr to 550gr ... all readily available plus there would be atleast two built so we can split reamer costs. Now if I can shift some other stuff out of the safe ... well that may all change

... and No3 is my lucky number

Cheers...

Sending goodies like that in the mail will get us both in trouble. Local importer of Speer projectiles will bring them in if ordered ... but wont give a price!! The 458AR will do ... for now! Just waiting on Manson

LOL, i don't think anyone would be confused.. the 6mAr (mmar? was that really a well though out name?) would drop clean down the neck of a 470, and down the barrel of the 500...
heh, now, a semi that shot them would be kinda fun, but not legal anywhere in africa to hunt with
