Hog Killer and I shot the 470 AR today...

80 days, idea to all shooting!!!

we'll do some load dev perhaps next weekend


your AR rounds all live
416 AR - 400gr at 2470FPS 26" barrel
458 AR - 500gr at 2326FPS 22" barrel
470 AR - 500gr at (something better than 2326) 26" barrel


All feed perfectly from rebarreled, but box stock ruger 77 mkII 7remmag actions


kick a$$!!

Yahoo Jeff
Sounds like the 470 should beat the 458 by 100 fps with the longer barrel and the bigger bore diameter. You've done one hell of a job. I like the 416 to maybe rechamber my Taylor. I'm thinking a 350 Swift at 2650 fps.
Take the best of care and Happy New Year
Dave

share the scotch with hog killer and have another for me...

well done and enjoy the satisfaction of a job done and daring to do something different!

p.s.

why be coy with the fps?

Will you be able to get 3 down in the magazine on a W70 or Ruger 77?

BS,

The 470 was just "born" today, be patient.

Hog Killer

PS: Good of you to send jeffeosso the scotch. I am sure that he will share a dram, and you will be remmembered for it. Now go get that BLR for a 416AR.

money permiting...

Congrats jeffe! Great way to end 2005 and ring in the new year!!

Looking forward to hearing more results as you play with the three AR's.

Cheers,
Canuck

so next is 375 35 338 and 30?

2 months?

fun times ahead...medium bore board here we come...

watch out bear elk and deer

so maybe 2650fps with 300 gr in the 375 a.r.? basicly 375 weatherby power?

Hey now! That is a great way to start the new year. Which .470 barrel did you use and do you plan to leave it at 26 inches?
I am very excited about the whole development and very happy to own one of the early versions.
Would it help you any if I sent you some UM Brass?
Anything else you might need to continue on?
Party hard and be safe,
and tomarrow will bring another day for having fun..

Fireworks are good. But a bigbore send off to '05, now that is fantastic!! And the new year in with a 470, is classy!
I wish you the Bubbas and the STC Hunting Club a happy new year!

Happy new Years all!


BS,
What HK said... it was just born!! heh, and

LOL

can't imagine not sharing it with HK... and the Bubbas!!

I won't start the 30's until the 40's are pretty well done and understood. Reason being is I don't want to be distracted from the 40s.

Dave,
Thanks.. I think tops loads will close in on 2400, with the 26". Since this is Frank's gun, and he was nice enough to let me to this quick load dev, we'll have to wait till I build another 416 for me.

Snowwolf,
I am certain that I can get the 3rd one down on the ruger 77. there's nearly 3/16 or better, of dead space on the floorplate/follwer contact point, but I need to do some head scratching on that before I start whittling! I THINK the 70 will take 3, as it will take (with various boxes) 3 down with the 338 win or with the wsm rounds.

Chris,
Out with a BANG ... and in with a 470 ... You know Dave's Mbogo started all this ... I won't tell Jana, so she won't beat him with a bar of soap in a sock!!

Frank,
Tried calling your cell a couple times.. right to VM on friday. I used the pacnor 1x18 twist .. but I don't remember if it's a 4 or a 5 ... it's rather light (7# 11.5oz)!!
I'll leave it at 26 for now, as I wanted to see the max barrel length *I* would use in a hunting rifle and how it performs. Anyone want a 24?
I am good on Brass, and I'll be handing you some cases in Dallas! and I did party safe


366,
Yeppers, excellent way to finish/start the new year... 2005 - Finished the first AR guns. 2006 - Load dev and field reports!!

Happy New Year and Many thinks

jeffe

Thanks Jeffe, We have been without electricity where my cell phone originates due to some winter storms so my cell was offline. I will try and call you in a little bit. I may take you up on that 24 inch or even the 26 which along with my 416 would be a switch barrel system of sorts for me.
Frank

Jeffe- Great job! Told you that shoulder would work! Maybe I should turn two barrels down and punt them in a CZ O/U barrel block for the 589. Now that would be cool.-Rob

Congrats Jeffe,

Great way to finish out the year.

Jeffe: As the local cops say on the scanner: Kyule.

This is the one I was hoping to read about...

Excellent.
Happy New Year!

We just MIGHT be doing some 470 load testing next weekend... won't be able to tomorrow, and that's my last day off.

For those interested in the technocal aspects, the 470 ar has more shoulder than the 411 hawk/400 whelen...

jeffe

great to hear...when you can please post some pics of the 470 rounds. thanks

Jeffe,

Good job, I want to see the shoulder on the 470, as I may just build one for grins, not that I need an other big bore, but have nothing in 470.

I have some ultra mag cases and will be back home tomorrow and will rubber band some together and post what I think the dia should be, want opinion. I think I posted the dia of a box I have that I think was an Sunny-hill box for an ultra mag, but its real long. I want to get my ducks in a row and build on a VZ that will hold 4 down.

Again, very good job and thanks for you time and thanks to Hog Killer also.

Lets also try to get a conf call to Jamison next week if it makes sense on the basic brass.

Call me tomorrow eve if you can.

I am up for some brass but I really like the idea of having the AR stamped on it. I would want 200 pieces .416, 100 each of .458 and .470

.375 AR
.416 AR
.458 AR
.470 AR

Hat off to you, Jeffe, to the job AND your efficiency!!!! Actually, the last impresses me more than the job itself!

Happy New Year yo you all!!!!

Bent Fossdal,

When jeffeosso post about making a wildcat cartridge up, he is not "joking around about it". (Unlike some ) It's going to happen, if at all possible. He has 5 wildcats to his credit in '05. I think '06 may see some more jeffe wildcats.

Hog Killer

just made 40 pieces of 470 ar brass, and 30 more 458 ar...

i reckon i'll get some help with it next weekend, weather permitting

jeffe

yeah.......it maybe to hot .......south texas, go figer

pics please...

Jeffe,

Any plans for a 7mm AR? I noted you want to finish the 40's before moving on to other projects.

And I don't remember whose it is, but someone has the tag, "The AR series of cartridges...ridding the world of 7mm Rem Mags one at a time"

I'm interested!

friar

that was paul h...

hmmmm 7 a.r. probably about the 7mm dakota velocities with cheaper brass

http://www.cpcartridge.com/7mmdkaP.htm

Friar,
since the 7rem is already over bore, and there's the 7 weatherby mag (yes, there is.. just never caught on) the overlap would be small.. besides, even the 7 wsm is overbore..

I am thinking to finish the 40s, and start looking at the 30s.. BUT .. we start getting into overbore/non-advantageous in normal barrel length. I mean, it's hard to get a seat on the "308 mag" train...

for example, the 30-378, 300 RUM, 300Weatherby, 300 winmag, 308 norma/30/338, 300 wsm, and 300 HH .. all "right there, go buy it" rounds..

311 imperial (precursor to the RUM rounds) covers the 303

8remmag/325 WSM - just about nails the 8mag space ... but there's room

338 - from 338-08-338/378 ... it's ocovered, but there is NO wsm here...

348 - NO

9mm (it would actually be .358, not .356) .. interesting

9,3 .. here would be a neat space

375 - would be a 375 weatherby in a standard action...

Jeff,

Awesome! I was out of the office for the week and just got your message, and caught this thread.

As to the 7mm rem mag solution I refer to in my sig line, it is not a bigger chamber I'm after, it's a new barrel with a 40 bore

358 AR would be cool, I'm a 35 nut and can see the use of something with a we bit more fuel than a 358 Norma, say 270's @ 2700.

That might fit the bill nicely!

Good luck Jeffe...keep us posted!

Cool.
Two guys besides me who like Scotch!

Life is good!

enjoy! you deserve it

any more load development or velocity updates this weekend?

BS, while you were making your last post, we were out shooting the big bores.(film @ 11)

I will let jeffe post his info. for his rounds.

Hog Killer

Jeffeosso,

Would the 470 AR fit into a Vanguard action?

sounds like a great round.

Congrats!

Snapper

I have got a .375 Whitworth Express waiting to be rebarrelled for the .470 or a .458 Express waiting.
I can't wait to get the 416 AR out to compare with my old Taylor and my new .416 Rigby.

Poor Jeff, never really had any vacation time during the holidays.
