Has anyone that had a NON-winchester factory 470 capstick been able to match factory/spec loads?

Jeff:

I was toying with the idea having Wayne build a .470 Capstick for me a couple of months ago but gave up on the idea, at least for now. Although I have never heard of anyone having a problem with extraction, except for the "ghost shoulder", the case is pretty nearly straight and that does not bode will for positive extraction. I guess I finally concluded that the .458 Lott is really a better design with a much better bullet selection. Problems is, I just don't have any interest in a Lott. As you stated, the .470 Mbogo is great as well as your .470 AR. Both are a bit better I think.

jeffeosso,
By "factory/spec loads," do you mean that data found in the A-Square manual, Any Shot You Want?

I can say yes, with H4895, very close, but powder lot variations, rifle barrel variations, etc., etc. ...
I feel another scan of an old "braggin' target" and note card of chrono data comin' on ...

I have some updated case taper data for Dave:
470 Capstick:
.513" just above the belt,
.499" at neck-1,
therefore .014" case taper between those, over 2.160" run:
Only .0065" case taper per inch.

But the .404 Jeffery case body taper is only .0075"/Inch.
The .416 Rigby and .338 Lapua have a huge taper of about 21.5 thou/Inch or .0215"/Inch.
About 3 times as much taper as the 404 Jeffery.

Even the 470 Mbogo and 500 Mbogo have slightly more taper than the .404 Jeffery case body: .0080"/Inch.

If the 470 Capstick has only .0065"/Inch,
and the 404 Jeffery has only .0075"/Inch ... OK? bewildered

My 470 Capstick has a McGowen barrel, heavy sporter, 26" length, 1:10" twist, works good. tu2
Rifle action M70 Classic Winchester







See that my McGowen barrel was tight enough to shoot well with even the old North Fork .474" diameter of bullet.
They are now .475".
My velocity and accuracy might be even better with those .475s. Cool



And if you want all the taper of the .416 Rigby and .338 Lapua on your 470: "470/.338 Lapua Magnum Unadulterated,"
aka
.475 Tornado
aka
470 Lapua

Con had a 470 Capstick built on an old Remington action and factory BDL stock. I think it was an 8mm Rem Mag

It shot very well, accurate and surprisingly didn't split the stock either.

But by hell it used to boot the crap out of you, the barrel profile was almost factory, a very light gun.

He used to get that thing really smoking, I'll see if I can get him to give some more detail about the gunsmithing

It's an impressive looking round.

My M-70 was built with a Pac-Nor barrel IIRC, and I've not encountered any problems with an oversized/undersized bore or chamber.

George, you obviously picked your gunsmith well! I can't think of anyone more suited to build a reliable bolt rifle like that.

I didn't get it smokin' because it used to cheese grate my knuckle! I ran about 2100fps. But the guy I sold it to decided to see how fast the 24" Lothar barrel would go ... 500gr at 2500+fps using Varget. Chronographed.
Cheers...

Well all of you know what mine are by now no doubt. What I actually sorta forgot about is 5 yrs ago I had SSK build a 470 Capstick on one of my Ruger #1s. I am only showing shooting shooting a total of 10 rounds thru this gun on 12/16/05. Then I put it away. Now back then using 88/RL 15 gave me 2304 fps with a 500 Swift. I was pretty well convinced that I would look at my 24 inch M70s (you know, the oversize bore guns) before I cut them back to 22 and 21 inches, that the velocity would be less right? Same thing, 2300 and change with the same load in the Winchesters with over size bores.

Looking at the old data from 2004 and 2005 on the Capsticks I got a lot of different velocity readings with the same load depending on the brass. Quality 470 brass would give 2250 fps with this load, 416 Rem brass gave 2275, and 416 Nic brass would give 2314 fps. That is about as fast as I ran them in those guns.

No, I have not slugged them yet! I probably won't until Sam comes down! I have more pressing matters at hand.

Thanks RIP. What do you think? Good DG cartridge or not?

Jeff, how much taper does the .470 AR have?

Brain cramp! The gun was built by George Hebel, not George Hoening. Sorry!

Dave,
The 470 Capstick has more taper than the 470 AR, eh?

Well,
Terry Weeweeland might object on theoretical grounds, regarding extraction.
Having reconsidered this,
I think that even just .004"/Inch of taper is plenty for extraction.

Another concern: Feeding
The 470 AR's bottlenecked shape would be a better feeder than the 470 Capstick.

The 470 Capstick has little taper and ends in a blunt, parallel-sided neck. Clumsy!

More Weeweelandishness or real handicap? stir
