boom stick.423-240 Weatherby. Newer pic's!
i think a new mountain molds design needs to be made...i figure a conical nose .35" ish meplat with minimal a .423" base to crimp sounds good.
01 April 2007, 15:37
Bent FossdalYupp, now we are talking! .423 makes all the sence in the world! I still vote for "Stright Belted"!
.404 Capstick is also grand!
This kind of brainstorming is fun!

i am sure we can get you a few cases bent, just a matter of time.
it would be neeto to see the 404 capstick aka 423-240 wby
hey...we could just stamp a 4 in front of the 240 for a .4240 wby mag...heh that is cool
424 wby...only one thou off...not bad.
424 weatherby...hmmmmm...

.366torqueNot trying to be the skunk at a garden party, BUT, shouldn't there be some taper to a case?
A 423 is pretty much a straight case with the 240. The 416 or 411 would provide slightly more taper which is beneficial for extraction, no??

Again, many drawings are wrong. When measuring live cases, the taper of the .404 Capstick should be about the same as the .470 Capstick.

ramrod340If my calculator is right using the numbers on steve's pages I get a taper of .006"/inch for the 470. Using my drawing for the 3.34" version of the .423 the taper is .0029"/inch and reduces further to .0026"/inch for the 3.6"OAL.
Just for comparison a blown out 06 forming a 400 whelen with a .458" shoulder would taper around .006"/inch.
As usual just my $.02

Ramrod,
Just found this in another thread on the .400 Whelen, I guess this is the source for my thinking.
quote:
Originally posted by boom stick:
Whelen states that the Howe-made dies necked the cylinder cases down very nicely and an effective shoulder was formed. In this incarnation the .400 was a very efficient round. When mass production was attempted, it was found that the case “could not be formed with sufficient exactitude in quantity production, and positive and accurate headspacing could not be assuredâ€. He termed the .400 Whelen a failure. Please note that he did not say the design was a failure. He said that the mass production methods available at that time were not exact enough to make a shoulder as good as could be done manually in the hands of an experienced reloader. With the recent introduction of cylinder brass by Z-Hat Custom and the increasing interest in this caliber, we may be seeing the old cartridge rise from the dead cartridge pit.
With modern equipment, then, a piece of cake - just at you say!
Oh, and do not always take the measurments from steve's pages for granted - they do not always equal live brass!

Yea, no probs, Boom, but I bet Paul would be willing to do it to, and he is a bit closer on the map!
Anyway, my full address is in my tag-line.

14 April 2007, 13:13
Bent FossdalI really do not have all the stuff needed to do this, but I'll make the tools needed!
Will be fun!
And Paul, I still think you would have troubles getting a factory to load .416's in the '06 case...

Darn I must have missed class the day we were told we were working on a round for factory chambering.
You are right for a number of reasons I doubt anyone would take an 06 to that level for factory. Slop in chambers and cases being a major one. However my case in 416 has the same shoulder as the 411Hawk. Again I see either of these rds as custom. Besides no one wants to hear that an 06 case can almost push those heavy bullets as fast as some of the huge cases and powder charges. But the 400 Whelen discussion going on the Bigbore has got my blood moving so I think it is time for a 400PDK.
As usual just my $.02

switch barrel an 06

27 April 2007, 10:07
boom sticki stuffed a 423 bullet in a 240 case trimmed to 2"...i think the 404 might work...(fingers crossed)
404 capstick comming soon...
27 April 2007, 11:26
boom stickfor cheap brass and necking ease i am wondering if it would be better to cut a belt in 06 basic brass...do a taper to a 10 thou belt and use altered 405 win dies...any thoughts? maybe 9,3x62 or 66 brass because it is wider?
27 April 2007, 13:35
Bent FossdalHeck, Boom, if I wanted to be cheap, I'd get a .416 Remington and never look back.
If this work I am going to get a reamer and make a gun el prompto, and I am going to use original .240 Weatherby brass. Believe me, life is to short to fiddle more with brass than necessary - just ask Paul about his .350 Rigby!

it will need to be taken up slowly and i dont have the tools for it to do it proper here...
i am shipping it tomorrow. good luck!
27 April 2007, 14:16
boom stick
here it is with the first .6" hacked off but necked to 423 and the bullet loaded as if the brass was 2.5"
sorry for the bad pic
no that is not pergo...
28 April 2007, 06:01
boom stickjust shipped...
29 April 2007, 23:39
boom sticksomething i find interesting about the 423 version is it is the largest cal you can do unless you have a serious rebate on the .470" bolt.
these 350 gr woodleighs have a decent s.d. (.279) and would fly fast enough to kill anything
the solid mono's will eat up too much room in the cas but these should fly at what 2250? 2300?
well, any way you splice it the 411, 416 and 423 versions will be capable of the 4000 f.p.e. benchmark
the 411 has the advantage of pistol bullets and using 405 win dies so it has the "cheapest wildcat" award.
02 May 2007, 23:32
Bent FossdalBoom,
If we can make this .423-380grs North Fork do 2200 I'll be happy as hell!
The .411/.416 version I'll make just to see how they look, and to dream about a factory round! For a custom round, the '06 case is so much better!

so the name is...
404 thor?
02 May 2007, 23:50
boom stickbent...the woodleighs will have less bullet in the case. the north forks will be good for loading long with its many crimping options.
oh, if you are making a 423 version can the thread title be renamed 423 or 404-240 wby?
03 May 2007, 00:51
Bent Fossdalhehe, well, colorful names are more your and RIP's departement. I like . 423 Stright Belted, .404 Capstick or somthing like that......
Yea, the woodleigh looks good, but a bit light for my liking, but if it looks goodAFTER expansion , I can go with it. SD numbers for an out of the box bullet is not interesting at all. High SD on paper counts for nothing if the bullet expand to much on impact.
I got some old, many times fired .240 brass from a customer - good to play around with before I start on the brand new ones from you!
Tried to expand one with bullets from .264 and up - front end first - and it cracked at .375.
I am now making the stright bored barrel end to fireform them from factory to stright in one boom!

boom stickgetting it straight will be tricky...but i am sure if it can be done you can do it.
sooooo will you be doing jeffe's corn meal styrofoam, point up and boom or do you have another proprietary way?
what are the chances of splits if fireformed straight?
will you neck up to 9,3 or 358 before fireforming?
03 May 2007, 02:20
boom stickp.s.
we should not forget the 10.75x57 belted for mausers...
i necked one up to 423 at the 57mm mark so it can be done...
240 wby case, 10.75x57 belted, and the 2" short action version
looks like a smaller 458 win mag...virtualy identical proportions.
04 May 2007, 17:18
Bent FossdalOK, a bit exited! Glad I got the old brass to play aroud with, as it was hard to get a load that did open but not crack the brass.
Here is a pick taken with my phone, sorry for the quality, we'll make better ones later.
.30-06 opened up to .416, .240 Wea'by opened up to .416, both 350 grs Speer, set at the cannelure.
Right, the .240 opened up to .423, with a 400 grs bullet from RWS set to the cannelure.
Same round next to a .458WinMag, bullet seated to 3.340".
Remember, theese are not the final rounds!
