311 imperial magnum?

[ratherbefishin]

Anybody remember the 311 Imperial magnum?I ran into it years ago ,sort of a home grown Canadian product based on a 303 british.I don't know what ever became of it though- the guy I know said it was a good elk cartridge-and he had taken several with it

It was not based on the 303 Brit. The only thing in common is the bullet diameter.

The 311 Imperial is more in the class of the 300 Weatherby with "fat" bullets.

 

[Why not?]

The bullets were indeed .311" diameter, however the case was a blown out 404 Jeffrey.

It was marketed by Aubrey White.

It led to a family of Imperial Magnum cartridges.Todays ultramags are virtually identical in dimensions,and performance to the Imperial Magnums..

 

[ratherbefishin]

did this cartridge ever attract any following-or was it just another wildcat that seemed a good idea at the time?

Right! However, they were all preceded by Canadian barrel maker, Bevan King, by at least fifteen years. He was building 35-404 Imps on BRNO ZKK602 and P14 Enfields in the late 70s.

The 35 Imp drives 250 gr bullets 3300 fps with ease. You would love that with with TXs, Stubblejumper!

Yes, I remember those. Looked at buying one but never did!!

I know someone who's got a 303-winchester mag. basically just necked up a 300 win to 303 in a p-14 action.

 

[stubblejumper]

I have always wondered why anyone would bother building a high velocity cartridge to shoot the .311" bullets when there is such a poor selection of bullets compared to the .308" bullets.

 

[slicknick]

Sheer patriotism I suppose. As well, remember that a couple decades ago the .303 was a lot more popular than it was now and there was more bullet selection. Like those Imperial 200gr loads

Just remember that those bullets were designed to work at 303 british velocities and would not likely hold together at very high velocity.

IIRC our fearless leader, Slavex, had a 303 IM. But I confuse easily.

 

[Gibbs505]

Speer had a 200 grn Grand Slam I recall in .311.

 

[Ultramag]

be a fun round for sure, but without good bullet's.............

Yes Dosing...............one of the mods had one.............Dan belisle too I think. A friend got one in .338 on this board from EE.

Well, I imagined i had one, does that count?
The ballistics were very impressive. But, I could't see it lasting, and I was right.

Nosler made a run of .311 Partitions just for this caliber..... Kimber of Oregon made the rifles (for the wealthy) and Sako chambered (for the rest of us). Imperial IVI made ammunition and brass as well as RWS. They were ahead of thier time, with a rebated .404 Jeffrey, but could not compete with Remington, who took the idea and could produce "en mass".
I had the opertunity to shoot a .360 ICM in the day, it was a Kimber serial #NASS 0001 it was impressive, to say the least. I kick myself for not aquiring it, just for the collectability.
