LOL... Full length it would be a fatter 550 Magnum like Rich's cart and have a tad more capacity than the 600 Nitro.

Rodney... You might want to start a thread so we dont clutter up El Jeffes great thread.

Sorry El Jeffe

Qual Cart as a run of brass all headstamped!
I am sending my dies in tomorrow or the next day, and Pete will go ahead and form them for us!!

another day, another step forward!

I sent the dies out today .. Pete will be able to start making formed brass next week!
jeffe

Jeffe,

How is the hogue stock holding up in the 500? Is it the full al bedding block or the pillar?

Go Jeffe, Go!!!! My .458 AR baby wants to go to Africa in May.

FN safety is in place. Large second recoil lug is in place and seems to actually be staying on. Bedding is working. Has new custom scope mounts.

2.5x Leupold Compact and a 1.5-5 Leuopold IR scopes are sighted in.

Is shooting about an MOA with both cast and 425 gr Rhino solid shank bonded core bullets in a moderate load at 2400 fps.

Is ready ... just needs brass. Sure do appreciate your attention to the issue!!!

GLZ,
it's just the pillar one.. its taking the work, but i think the full block would be better.. then again, I think it would be better in a 25-06, so yeah, it would be good. Shots fine from the shoulder, beats you stupid from the bench

Mike, nice to hear the report.. hope it all goes well, and pete should have the brass shipped in a couple short weekS

Hornady making 416, 458, and 470 dies, Commerically available 500 AR dies, Headstamped brass....

WOW, I am feeling pretty accomplished on these

Your a good man Jeffe, me in Oz is eternally grateful .

Paz

P.S. for those who don't know, Jeffe has organized his brand new 458AR Hornady dies to be sent to me and he is back to waiting for another few months or so for his.

Say, did you receive the dies yet? If not, I'll be calling H on monday morning!

.500AccRel on the way. McGowen is at the moment rebarrelling one of my CZ 550s to .500AccRel. This one will have their 1 in 10 twist barrel ,CZ style knuckle for use of recoil lug positioning in stock and to recycle the factory rear sight. Also going with slightly heavier barrel profile to eliminate the shim or wedge to raise the rear sight to match the front. Even the guys at McGowen said this one was going to be really nice. It's even tougher waiting. Rodney.

Thanks mate, just checked and i haven't been charged for them yet, most likely still in the manufacturing stage somewhere.

Paz

I haven't heard back from Lonnie, but I am certain they they are finished, as they were finished in a group, with my other 2.

its certainly a snafu

LOL that bullet makes the 500 AR look like a 358 Win with the bullet seated out

Can't wait to see the load development with the BMG bullets

Breaking 2100 with the milsurps would be cool.

Dimensionaly the 500 AR is about 25% larger than the 358 Win but to be more dimensionaly correct the 458 version (458 Boom Stick) would be more of a scale version of the 358 Win.

458 AR Brass shipping TODAY -- 4/9/09 -- the rest will be shipping over the next week!

Congrats Jeffe! You've made one Eland in RSA VERY unhappy

Some recent reduced reloading data from my 458ar rifle. 22" A&B barrel, 1x14 twist, with fixed 2.5x leupold, converted ruger 7mag. Temps were in the mid 70's at 1160' msl. All with 375 rum brass and CCI large rifle mag primers.

Thanks Mike and Peyton
Peyton - I'll put these in ammoguide

Well, I'll list after Mike Haas adds 5744 to the site!

Peyton,
How did these mt baldy feel, compared to the 2159fps, and were the 2159 fps (vihtavaouri loads) more accuracte?

now on ammoguide!

cream puffs! I bet you could run these loads in a 45-70 trapdoor. When I pushed those 550's hard they stayed on the paper but the accuracy was pretty sorry. Could of been me getting punch drunk off the sticks too though. Unless I'm headed to africa its going to be 350-400 grainers at 2200 for me.

I love those 405's and will probably switch to a more conventional powder and try and run them around 2100-2200 for my "all around load". They are fragile at those speeds but I don't care.

On another subject. Has anyone that ordered 500ar brass gotten theirs?

pt, I load 68.0gr IMR 4895 in my Lott for 2112fps. I uses the crimp groove closest to the base. You might start with this load in your AR.

Keith

I don't know if the 500 AR brass has shipped, but it has been ran .. I'll check.

thanks for the info on the 550s.. Keith is making up some, from a lyman (i think) mold, and we'll try those, too.

405s at 2200 are sure killers ... just expect them to react like BTs

My 458AccRel dies arrived from Hornady, just need to find some time and give em a whirl.

Thanks again Jeffe, you have made one aussy AccRel owner a very happy man .

Paz

Paz,
You are more than welcome! Great to hear that! I'm am calling those guys today anyway, so I'll let them know.

Con, SF, and You can all load now!

Just curious guys I did some searching but can't find what I want to know. I have a nice springfield sporter(1,200,000 SN) in 30-06 and was wondering if the 500 AR will fit on this rifle. If this will fit on my Springfield does anyone know the apporoximate cost of the rebarrel. Any help is appreciated. This sounds like fun LOL

I have a 416 AR on a high SN springfield ..
The 500,though, has a larger bolt thrust ..

call mcgowen, as they have my reamer, and ask them if they would do it?

Thanx Jeff! Kind of funny my Springfield already has a Mcgowen barrel on it. I have been wanting a .416 Rigby but this might be more fun. Will Mcgowan have your reamer for a little bit? Thanx Again!!

Yes, sir.. they have it, and can have it on rather short notice.

The 416 is actually an easy one on that... get Duane or Tom to make you a mauser 458 winmag box, and send your action and a check to mcgowen. the 416 has slightly more capacity than the 416rem/416 ruger, and i believe ch4d has dies on the shelf.. but you can also order from Hornady -- no joke!

My suggestion, though, is the 458, as the dies, brass, and bullets are all reasonable.. and the rem 405, as a cheap and frangible bullet is a slayer at 2100 .. and easy to shoot!

Bravo!
How bout a pic of the line up of the virgin brass beauties...

Mine got here too! If Jeff doesn't beat me to it, I'll post some pics in the AM.

OK, ya'll have me convinced. Gonna be 458 or 470 AR.

Question: I have a Mark X 300 Win Mag action to build on. Any issues I need to know of? Will it take 3 down? How much feeding work?

Anything you've got to offer will be greatly appreciated. It's not gonna happen right this minute, but soon if the economy continues to show glimmers of hope.

Thinking 470 AR in a #6 PacNor at 22". Barrel band swivel, NECG Masterpiece adj. rear and banded front. Probably Boyd's JRS trimmed down a bit at the forearm and refinished. Extra recoil lug of course. Wrist pin, double cross bolts, full length bedding, etc...

Any more thoughts?

Thanks Jeffe and others for ideas, experiences and any helf you may offer.

David Walker

Edited to ask: Anybody got pics of loaded 470 AR ammo or pics of your finished rifle, etc...?

SHOULD be an easy build ..
How many 300 wins does it take, NOW?

The combo sounds workable.. i think i did mine in a #5, and its light.. light enough for me to like it, so a 6 might be best.

the JRS stock works well for recoil, but have a barrel lug installed.

470 AR


These are Neal's and my 458 AR on mark
X actions


I can suggest to you a couple guys to do this work, with Tipp Burns being high on the list...

Of course, McGowen could do the whole thing for you.

If it were me, I would order the dies from hornady, as those will take awhile, and start collecting 375 rum cases!

the 470 is probably the coolest of the 40s, but the 458 is the most practical! Though, honestly, the 400gr speer gold dot .475 bullet works GREAT for 99% of your hunting

Jeffe,

Thanks for the information. I've had a bad itch for a 450 or bigger for a while. My biggest now is a RSM in 416 Rigby, but with 450's at 2300, I figure a 500 at around 2150 or 2200 couldn't be much different. The 416 goes around 11 lbs. with scope, but I like it better without at 9.5-10ish. I figure somewhere between 10 and 11 for this rig, with irons only. Barrel lug for sure. I'll check the capacity with some 300 WBY brass as I don't own a firing 300 Win. I was dead-set on a 458 Win Mag, then I remembered this thread. As for the 458 practicality, seriously, since when does that really come into play when you're building rifles. Let's face it, practically, I'd just go pick up a CZ in 458 WM or Lott for a few hundred less than this project and have fun with it. But, practical I ain't, just ask my friends and family. LOL!

Thanks for the help. I'm sure I'll have more questions. Gonna order 20 pcs. of 375 RUM this afternoon to play with, maybe get the dies ordered next week.

OK, so what's it gonna cost me to get you to make me one of those stocks? Seriously.

Gotta go drag a disc for a while. Check back in tonight.

Thanks again,

David

David,
my stocks either take 4x longer than i wanted, AND or look like they've been chewed by a drunken beaver.. i only turn for myself, as the worst of the professionals is 5X better than me ....

the cz, in 458lott is TOUGH to beat.. but the 458AR lets you do it all in a standard length action, as well as the 470 ... the 500 requires more work, plain and simple

nice thing is you can send boyds a stick of wood, and in awhile, get back their pattern, and it works pretty good

Understood on the stocks.

I'm really just not crazy about the CZ's. Just don't care for the feel of them, the stocks. Damn fine rifles fas as I'm concerned, just don't like the feel. Probably could drop it in a McMillan and still be more economical, but what the hell.

I checked the magazine and it'll hold 3 300Roys with room to spare, but not #4. It'll take about 2 1/2 Rigby cases.

I'm still thinking about a Ruger for this deal. My 416 is a Ruger, so it would make sense for the "big sister" rifle to be the same basic action and operation, especially in a pair of DG rifles. The 375 H&H is a M70, so that's close enough. Would the Ruger action truly be easier to make feed, magazine, etc...? If so I might just go pick up a beater Mag and go that route. I can sell the Mark X action and offset at least most of the cost, I think. Probably easier stock options for the Ruger as well, even the Boyds and McMillans. What I was talking about with the Boyds was reshaping the forearm, as in shortening and maybe thinning a bit as it looks like it may be a little thick. Haven't seen one in person.

Thanks Jeffe. Any more input is welcome.

David

dang, if you can get 3+a bit, you should be able to get 3 of the 458 or 470 ARs in the mag.

on the CZ, i was just trying to be the voice of reason (HA!) ..

I think you are at an even starting point, markX vs ruger, at this point. rugers have gone up, a bunch, since I started this project.. you could get a 7mag mkII for 250-300 bucks at any gunshow in 2005.. and now thats closer to 400. The ruger is an easy palce to start from, seriously ... though several guys have done them on mausers (me included) and they worked out great.

so, for the action, if you are going to "kill" one, I would prefer the 300 to stay together and the ruger to be the donar .. that way, the best results stay huntin!

I'll say it again, though, the 458 has the most bullets, but the 470 is cooler!

Jeff,

Just to be sure we're on the same page. The Mark X is a barreled action in line to "be killed". I don't have a space Ruger lying around, I'd have to drop $400 or so to pick one up, and hopefully sell the Mark X to offset some cost. The Mark X is a 300 Win Mag that I bought as a complete rifle for $250 at a local pawn shop. I scrapped the stock as it was pretty rough. The action has some surface freckling and the barrel has a little more, but nothing that wouldn't clean up easily.

I'm trying to weigh my options and look at costs from one to the other. I'd want a 3-position safety on the Mark X, but that's not really a big deal, nothing money can't fix, right. Beyond that, it seems to me it'd be a wash from a cost standpoint. Only thing that really concerns me is the stock thing with the Mark X. I'd like to do some of it myself, just for the fun and the hell of it. I like the JRS, but it has no checkering, which I do not like.

Oh, and tell me more about McGowen. Their prices are great. How is their work quality? From what I've seen of their pricing, I'd bout assume let them do it start to finish. Probably go with CM barrel and have the whole rig Cerakoted or something of the sort.

Gonna order some 375RUM brass to play with shortly. Then maybe this week order the dies. Anybody at Hornady that I need to talk with? Maybe the Lonnie, I think, fellow that ya'll were talking about?

Thanks again,

David
