What are the Canadian Magnums?

mehulkamdarWhat are the Canadian Magnums?
This is another question from an inquisitive Indian hack - Cartridges of the World has page after page in both it's 8th and 9th edition on these cartridges but no one else anywhere seems to have any information. I even tried a number of search engines on the internet but got nowhere. Could anyone please give any info on these? I shall be saving the information for it's archival value.
Thanks in advance,

dan belisleThere used to be a company in British Columbia (BC) here in Canada that marketed a series of cartridges based on blown out and improved full length 404 Jeffry brass. They called them "Imperial Canadian Magnums". This was a few years before Dakota arms, if memory serves me correctly. The 'smith who did the actual work is apparently still making these in BC. If you do a search on the forum you can probably get his name. If you think Remington Ultra Mag Improved, you'd probably pretty much have the idea. Calibers marketed were 7mm, 30, 311, 338, and 358, I believe. Maybe the 375 as well. - Dan

CanuckThey are still made by N.A.S.S. (North American Shooting Systems) out of Osoyoos, BC. I saw them last easter at the Calgary gunshow. I can't remember the fellows name, but I have his card at home.
The are based on the 404 case and are very similar to the Ultra Mags etc. The marquee of the line up is the 311 Imperial Magnum which uses the .311 bullet like the 303 British, of course.
I think Dan hit all the calibres they offer presently. I did not see a 375 in their line up, however.

<Matt77>WHen I first got that book, and the RUM cartridges were coming out I "sensed" the similarities. Funny how things aren't really ever trully new.

dan belisleNot much is Matt. I also recall a "338 Abe Express" from some years back (before the Imperials came out) that was based on the 404 case as well. - Dan

Wasn't this the same type of rounds as Mr Seyfried& Siatos G&A line. I guess they are all based on the 404, but with idfferent shoulder angle and neck lenght.
Saeed, What is the configuration for your loved 375-404? Same as the G&A, Tell us, don't be shy ![[Big Grin]](images/icons/grin.gif)

JackMI'm a little confused. I got a complete, I believe, collector's set from the late Norm Walden. There's the 7mm, .300, .311, .338 and .360. The .360 uses .358" bullets. Yet Cartridges of the World #9 shows a .375 and omits the .311 and .360.
Mr. Walden told me that the company got into trouble when they contracted with an off-shore company for brass and it came a year late and too soft.
Speer made a 200 gr. Grand Slam for the .311 for a few years. Gwynn Davidson, formerly a Regina, Saskatchewan gunsmith made a .35./404 some years before the Imperial Magnums came out.

<JOHAN>Gentlemen
I have seen a sako built in 300 for this company. It's a very nice gun
Norma made the brass. According to them the company couldn' show up enough money for closeing the order. Norma ended up with loads of brass and no customer. I guess the company went bankrupt

SaeedJOHAN,
I have no idea what the G&A is, but ours is based on teh full length 404 case, blown out and necked down to 375, 338, 30 and 270.

<JOHAN>SAEED
I think it the same thing, a blown out 404. Tell us more about your famous 375-404
The G&A were designed by Tom Siatos and Ross Seyfried, If I'm correct
How is the penetration in the higher velocities. How long is the neck of this round and chest angle.

I think the Russians have the ultramag version ![[Razz]](images/icons/tongue.gif)
There is one called Baltica 9, a barley wine, or as explained to me, beer with some Vodka added. At 20% alcohol, the 500 ml bottle hits pretty hard

jeffeossoThe Imperial mags are basically the same as the RUM. I've held several flavors of each, and they are like trying to determine WHO's version of improved 300 HH is which.

Stop thinking about beer and tell us about you 338 G&A. I have asked you once before but you are trying to slip away. Don't be shy

Paul HJohan,
I've never had a 338 G&A. I do believe that John S does use one.
Right now I'm just down to my 350 Rigby.

sorry for mixing up the names. On this forum some people swap name everyday
How do you like the 350 rigby. I guess you can get higher velocity than a 358 norma mag? Tell us

Paul HJohan,
I love the 350! I haven't pushed it to see how fast I can drive bullets. The rifle started as a 35 whelen ackley that would only group 250 gr bullets when loaded to 2700 fps, which was too hot. Now I can push 250's to 2700, and at a reasonable pressure, and it is also much more accurate after Mr. Rick's did his magic to it. It will print three 250 gr hornady rn into 3/4" at 100 yds @ 2700 fps even. I also like the way the gradually tapered cases feed so smoothly.
The case capacity between the 350 Rigby and 358 Norma is essentially identicle. The Rigby may hold another grain or two, but that is insignifigant.
