new gun??? what is it

[yellow dog]

went to the gun smith today, he was slow so he went ahead and cast the chamber for me, only took an hour or so and was done differently then what I presumed would happen. I thought he would do it with wax or plaster, not molten metal.

any way he says he's seen them before. they were built in the Redmond ,OR and bend, OR area in the 60 and some of the 70's. I guess folks were coming out with there own line of wild cat bullets
left and right around that time lawyers hadn't got into it at that point. he also informed me that the powder there loaded with is old military surplus 20mm cannon powder.

its not quite a stw as its not long enough.

not real sure as to what I will do with the rifle right now but I think its pretty cool

But it is a 7mm?

7mm-308 norma?

It seems to me that I remember reading somewhere that Hodgdon 4831 was originally military surplus 20mm canon powder.

Seems like a cool cartridge though, no matter which one. There were ton's of wildcats made back then. If I didn't have a 7mm Rem Mag and a 7mm WSM, I would love a 7mm Mashburn. Not that it does much more than any of the ones I have, just cause it is different.

Am I the only one lost here????????? Did I miss a post? What is it we have.?

 

[yellow dog]

elk man it would be close to a mashburn. but it was some wild cat made by a central, OR smith by the name of Mr. Burris in the 60 and 70,s not sure there is real name for it ( the cartridge) as its kind of a loner.

 

[yellow dog]

fotis it is a 7mm bullet

 

[Elkman]

I probably have reloading data for it, and so will a couple of others here. !!! I will take a look and see what I can find.

 

[yellow dog]

elk man that would be great as it is a very cool old gun.
im very interested in the off brand stuff anyways and this is as off brand as I like to go.

I think I will have it stamped for the next unsuspecting soul as its stamped right now for a 7mm rem mag
I sent fotis some pics to see if he could post them, seems this simple task is beyond a simple minded folk like myself

 

[Elkman]

My 1962 Ackley "Handbook for Shooters and Reloaders, says the 7 mm Mashburn Mag ( Long) is made by necking the 300 HH case to 7mm and leaving it full length. It is longer and has greater capacity than the 7 mm Weatherby and probably less efficient. Use Weatherby data.

It should be easy to load for, and suitable for most anything in the US.

Is it this possibly? The company made quite a few caliber choices.

7mm ICL Wapiti
The Wapiti is a more complicated wildcat based on the .300 H&H Magnum being necked-down, trimmed, and then fire-formed. The large case is well-suited to heavy bullets. Performance with a 160-grain (10 g) bullet is approximately 3,225 ft/s (983 m/s).[21]

elk man,

Don, the gun smith said the same thing about following the Weatherby stuff.
not sure I will invest in dies, (Not sure who I'm kidding by saying that)
throwing a 160 AccuBond or 168 ABLR @ 3200+ would be a real game changer that is for sure. if its possible.


OU812 The I. c. l. stuff is cool but the neck angle is all wrong!

 

[OU812]

Well I had to try.

 

[yellow dog]

It is a good guess and I kind of wish that was the case. sounds like a neat well thought out line of bullets.

If it's a Mashburn you have something pretty darn cool already.

posting pictures for Josh

 

[OU812]

I like it. 7mm WTF. :mrgreen:

 

[FOTIS]

I know funny huh?

 

[Elkman]

I am sorry to throw cold water on the discussion but that does not look like a 300 HH case "necked" down to 7mm. The HH has a long slow taper, this one seems more sharper and pronounced. What do you all think? I am thinking there is an HH case there, but fire formed to fit the chamber. Makes no big difference, the cases will have to be hand made anyway. I am thinking a Mashburn "Super" Magnum. Neck a case to 7mm, load and fire. Instant case, send that to RCBS and instant dies, then you are ready to go.

 

[yellow dog]

elk man I have 7 loaded rounds that came with the gun when it was originally built plus 33 once fired brass the original smith made with it.


it is for sure a 300 h and h case BLOWN out and necked down to 7mm though. all the case I chose to picture it with are 300 h and h prodigy cases.

the closet one is the 340 weatherby. so it is a full length case.
