Sorry for the bad pics.. it's late, and I couldn't find my good camera

remember, these are 3.35" long and have slightly more capacity than the 416 rem, 458 lott, and 470 capstick

458 AR with 500 gr hornady
470 AR with 500 gr Woodleigh

Jeffe,

Can you let me know what Tom would charge to rebarrel a 470 AR for me also?

Great work.

Hi Jeff
I still like the 416 AR. I'm thinking of rechambering my 416 Taylor to your AR cartridge.
Have you finalized anything with Jamison for brass and what are the final ballistics that you've come up with? You've done a fine job my friend.
Take care,
Dave

great!

thanks for posting pics

a great accomplishment worthy of admiration from everyone especialy those who has never done it

jeffe is no cold timmid soul

(name that refference and i'll send you a cigar)

dave, you have the right idea...

the 416 has a nice niche that has been underpowered till now...

the "mini-rigby" will duplicate the factory loadings and that is a big deal

Great job Jeffe. I am definitly going for the .470 as well. I have another Ruger for the barrel change.
Frank

Thanks for the picks, Jeffe!!

Good to see! That .470 should be a winner!

Hat off for you!

Hola Jeffe:
Say, have you split any Ruger 77 stocks yet with the ARs? Seems like it would be a weak point to me, especially with the .470. But that's based on seeing a guy split a stock behind the tang with a .338 about 20 years ago. I was at the next bench.
Bill

Bill,
not yet..
I put pins in the wrist and relieve the tangs. On the 470 (and 458) I put barrel recoil lugs in ...

but, funny enough, no crossbolts on the rugers...

I think those stocks are kiln dried, as teh are VERY chippy, though

jeffe

I thought the idea was a non-mag length round, i.e., 3.34". No?

Now that sounds good! How does an isolated Canadian go about getting a reamer or a barrel?

just be nice to jeffe and ask

Dave,
the brass deal is the slowest part.. but that will come together was well. the prelimenary 416 results, with a 26" are pushing 2500, and that's nearly zero load dev, as that's Frank's rifle!!

close.. you might have mis-read BS's post... we are NOT working with rigby cases

3.35" non-belted, cheap brass, and fit/function in a standard length action, withouth extensive mods, with something like the power of the rigby, the lott, and the capstick.

mission accomplished

366,
we can work that out several ways... PM me for what you would like to do

bs,
thanks

jeffe

The AR line of cartridges will allow the same rifle to be used for mltiple calibers if desired. I find that very appealing since it will always be a perfect fit once you start with a solid rifle to begin with.
Being sure to always call them by the correct name will eliminate confusion.

470 AR
458 AR

Frank

Well,
shot the 470 today, about 60deg.. rel 15 offered the best results, but..

even the top loads still presented heavily smoked necks and round primers...

500gr woodleighs at 2150

Will go to a faster powder next week!!!

2300 should be easy

jeffe

H-4895??

close, h335 next
jeffe

DAMN no cookie for me.

Jeffe,

has it been enough headspace on the 470 AR? meaning after firing the rounds did you do some measurements on everything (case and headspace) and it all looks good? I am not a gunsmith so don't know what minimum needs are on it so am curious how its proving out.

Going from the 264winmag, 7mm mag, 338mag chamberings, aside from rebarelling what exactly would be entailed? Above you posted OAL of 3.55, which would be longer than standard length, was that a mistype or just you having seated the bullets out longer, or did I miss something and that was the idea to start with?

PM sent too.

Jeffe built my 416AR on a Ruger 77 former 7mag. He is changing the box to allow 3 down.

That's what got me confused. Typo? I'm with ya'.

Thanks for letting me know on the typo.. got it fixed.. with no doubt, these are 3.35 nominal OAL.


I just got back from the DSC and spent some time with the 411 hawk, and meet Fred Zeglin.. on heck of a nice guy...

Trust me, the 470 has more than enough headspace... it ACTUALLY has more headspace than the HH belt, and more surface area...

once fireformed, it's pretty darn hard to make a mistake!!!

jeffe

I just got back from the DSC and spent some time with the 411 hawk

I HOPE YOU ENJOYED IT JEFFE. I met Fred last year and really considered having him build a rifle for me. I have been using Hawk bullets for some time and really think they are perfect for my hunting uses.
Frank

Frank,
I thought you didn't go? Dang it, I would have hunted you!!

I'll try your cell in a bit

jsut for the record, Fred makes the hawk carts (411 hawk) and Andy (no relation that I know of) makes the hawk bullets.

Mission Accomplished (M.A.)

470 AR (surplus h335)
500gr woodleighs
2200 - Easy as pie
2303 - my hunting load
2380+ - max load with h335

to recap
416 ar - M.A. - target 2400 - realized 2480+
458 ar - M.A. - target 2200 - realized 2320+
470 ar - M.A. - target 2200 - realized 2380+

all feed from standard actions

I believe if one experimented with a faster powder (benchmark or rel7) you could see another 20-50 FPS on the max loads


thanks for the tremendous support

the 550 express now has a "light" hunting partner

jeffe

Jeffe,
What velocities would you expect from the 416 with Barnes XXX 325-350 gr bullets?

Congratulations! In record time too.

I bet close to 2600 with the 325, maybe 25fps less with the 350. BTW, that's about what Hodgdon found for the Rigby, albeit at considerably lower pressures.
;-P

Congratulations, Jeffe; this thing went about as smooth as you could want. Now that you've seen the 470 AR fireformed, what are your thoughts on a full-length 470-404? It's always seemed "doable" to me, but right on that margin, "400 Whelen territory." I'm thinking .530" at the shoulder, .012" thick neck, for about .015" each side....
Take the data from Vincent's round, and add another 20-35fps per bullet weight. Or at any rate, a 500g A-Frame at 2400 from a 25" bbl without getting too hairy.

congrats jeff, outstanding ballistics. if i had a couple of stainless ruger actions what would it cost me to complete a rifle(stainless barrel,dies and your using the ultramag brass right..Also does pacnor intall a recoil lug?

Hi Jeffe. You have accomplished something to be very proud of.

No, I did not attend. That was a quote from your post above about the Hawk.

I am getting more interested in the .470 now. I just need to finish the payoff on the Westley Richards and I will start having a little extra to save for the build. I will contact you soon for your friends number for that purpose.

I hope you had fun goofing with the guys. I really missed it and spent yesterday shooting the new Rigby and my Whitworth .375. I am trying to decide if I like the Rigby enough to use it as the heavy and skip down to a light as a second rifle.
Frank

Hi Snowwolfe,
I can get 2550 fps with the 350 grain Swift A-Frames and 2400 with the 400 grain Hornadys so I would think if Jeff reached 2480 with the 400 grain bullets you could figure 2650 as a good possibility with Swift A-Frames. You may get a litle less with the Barnes because of their added length. I don't think I would bother with the 325's.
Take care
Dave

470 Mongo,
This is out of the 416 AR correct? Barrel length? I am trying to decide if the 416AR has enough advantage over the 416 Taylor to make the additonal expense of dies worth it.

Hi Snowwolfe,
The velocities I mentioned were out of my 416 Taylor. I don't know why I missed mentioning that. Probably the same reaon you did such a fine job with the spelling of Mbogo. The case capacity of the 416 AR is quite a bit more than the Taylor. The 2650 might be optimistic but if Jeff is getting an 80 fps gain with the 400 grain bullet I would think that a 100 fps gain with a 350 is realistic.
Take care,
Dave

time for some more scotch!

Would it be safe to assume the 416 AR offers almost a 100 fps advantage over the 416 Taylor? Are you guys with the 416 Taylors actually getting 2400 fps with the 400 grain bullets?

I'm getting 2400 fps with mine and I know Canuck is getting the same with his. I'm using Reloader 15 and have a 24 inch barrel. My barrel is fire lapped so that may give a 20 fps edge but that's about all.
Take care
Dave

Dave,
how did you firelap the 416?

thanks, as another 20fps would be AWESOME

Snowwolf,
my (former) taylor ran out at just over 2300

Snapper,
I sent you a PM

have you made drawings yet for the 375,358 and 338 a.r.?
