Well this is my idea, a heavily modified 7mm, 300, or 338 Remington Mag Case to forum a shorter 40 caliber (well .416) round. I didn't know what to name it so and I remembered how the US military used to name their developmental rifle names with a "T" so I used 40 as its the caliber and then since this is the 2nd design (shortened it from the first design) its the "E2" model. I'll have to come up with a name later on. ;)

There is a slight taper on the case, alittle more then the RUM's normally have as its the same taper over a shorter distance (base of the case is .550" not shown on the drawing). :)

Its pretty much a whole half inch shorter then the 416 Taylor. :)

With the help of a member on another forum and a couple of calculating programs I got the fallowing infromation:

Case Capacity: 80.3gr of water.
Case Capacity: 0.318 in ^ 3
Case Capacity: 5.211ml/cc
Useful Capacity: 4ml/cc

Powley computer calculated:
Charge weight: 54.3gr (DONT USE NOT TESTED!)
Powders good for use: IMR 4320, IMR 4895, IMR 4064
Best Match, IMR 4895
Velocity: 2,000fps (well 1980fps but its easier to do the math with 2000fps)

Using Point blank:

Energy at Muzzle: 3552 :eek:

Zero calculation:
100 yards = 4.62"
200 yards = 0.00 Zero
300 yards = -17.27"
400 yards = -50.43"

Recoil Calculation: 35.89ft/lb on a 10lb rifle, 23.92ft/lb on a 15lb rifle.

Taylor Knockout Factor of 47.54. :)

What do you think ?? :confused:

Edit: Its been named the 416 Canuck by the other board member who has been helping in its development! :D

Dave,

Sorry, this round is plenty strong enough for me, considering its at about the same level of the 416 Taylor execpt in a short action. :)

The 416 WSM has been done, so why not just neck up a 325 WSM to 416 and use that? I'd also suggest that the 50 degree shoulder will not form well, and is not as conducive to good feeding as 35 would be.
 
Andy,

You think I should go with a 35* shoulder then ?? :)

Well I rather not neck up and I've got a source of cheap (read free) 300 Remington Ultra Mag cases. :)

As well as about every other caliber!
The one that astounds me is the .450 Noveske in a light 20" barreled close range rifle!!:eek:

Yes - I'd say 30-35 degrees.

I'm not sure why you don't want to neck up, it's as simple as can be - anneal, go up in three stages (35 cal, 375 cal, 416 cal) with lots of lube, and you're done. With the 300 RUM cases, you've got cutting, trimming, necking down and probably inside neck reaming.

The Accurate Reloading "Wildcat" Forum would be a big help. Since it's all been done before , ;) there'd likely be some first hand experience to draw upon.
 
Well still I'm thinking it would be a good round. :)

I never heard of that forum I don't think, I'll have to check my email I might be a member there and I might not know it.

That's plenty of shoulder. The neck will be about 0.440" and the shoulder starts at 0.530". Belts are only 0.010" proud of the base (but at 90 degrees), and here you've got a 0.045" difference albeit at 35 degrees.

A 416 has been done with the 30/06 case (e.g. 411 Hawk), and headspaced positively.

Don't see the point at all. Full length 375 Ultra necked up would be usefull though.

I wanted a lower powered 416 out of a 300RUM case. If I was going to go higher I'd have simply used the 416 Taylor.:)

Well I have .035" of sholder on this, thats one of the reasons I decided to go with 50* to make it more of a sholder to try to headspace with, just made more sense in my head at the time. :confused:

The way I see it, wildcats should be wild. That's why I've been suggesting all sorts of outrageous things like necked-down 30mm GAU-8 casings and shoulder-fired wildcats based off antitank rifle configurations. They're wild, dangit! Wild!

My new motto should be: "You won't go dour when you've got superior firepower."
