Thank you very much for the update!



Thanks Ray. I’m getting ready to launch my revised website and I’m trying to make sure that I have identified things correctly before I post them. This info will help me immensely!


Webmaster note: Separate list of cases has been added to top of this posting so case types and cartridge information is on the same thread. Separate case thread has been deleted.

Ray approved this change.


Ray–I have what I have always assumed was one of the pre-NATO rounds using the SUPER SPEED .300 SAV case (C/L 1.866 inch–47.4mm). It is a Proof Load with a tinned case with an Extra Long red lacquered Pointed FMJ bullet and a red lacquered case head.

I see you do not list this cartridge above. Have you seen it before? Do you feel it is part of the Pre-NATO rounds or just a .300 Savage Proof.


This is a great list Ray - good to see you back.


John - I copied and pasted the missing items.

Ron - More than one of those “proof” cartridges have found their way into collections. I have one. I, and others, like to think they are legitimate pre-NATO rounds but I can’t say that I’ve ever seen any documentation.

My lists do not include any of the cartridges using the 300 Savage cases. AFAIK, none of them were assigned “T” numbers. There are others not included, including the aluminum cased cartridges, as well as some seldom seen, loaded in FAT cases. I tried to keep the list as simple as possible.

BTW, it’s not really correct to refer to the case lengths in mm. This form of measurement was not adopted until 1954 when the cartridge became the NATO standard. Even then, it was a practice used mostly outside the US.



Ray–Until proven differently, I think I will continue to include the Extra Long bullet .300 Sav. Proof with my Pre-NATO collection. I have a SUPER-X .300 SAV. Proof using the soft point bullet which I assume is the standard .300 Savage Proof cartridge.

As for using Metric dimensions, I agree with what you said, as far as official designations. I used both in my post in response to a complaint from some European collector (I don’t remember who) that felt that on an international forum such as ours, that when dimensions are listed for a cartridge, especially when an ID is being sought, that the dimensions should be in either Metric units or in both Metric and Inch units. I tend to agree with that and so I try to remember to not be so provincial as to use only inch, which, after all, is used by only a few countries any more.


That is superb Ray, thank you. I have printed this off and added it to my reference information.
