Re: 338 edge?

sniper2,

This is the story I find on the Edge... I'm not trying to be a wise guy, but it looks like S.C has the credit for the Edge. Here's his story, which he wrote; on how he did it'..., along with wikipedia for what that's worth.

History & Developement
I developed and named the 338 Edge in 2001. Now I am sure I was not the first person to neck up the 300 Ultra (RUM) case to .338”. I have in all probability spent considerably more time with the round than anyone else. Jacob Gottfredson wrote an article about my test rifle that published in the October 2000 issue of “The Accurate Rifle”, this article can still be viewed in the “snipers paradise” website. Since initial development we have been refining the 338 Edge to become the most practical “bang for the buck” available to the long range hunter/shooter/tactician.

Our first refinement was to move to 30” match barrel of extreme quality. We chose Hart barrels based on reputation and our experience with them and have never looked back. We currently use others as well but the Hart tubes are the overwhelming majority.

With the longer barrels we started running heavier bullets specifically the Sierra 300 gr. SMK. We can run the 300 SMK 2800-2950 fps depending on the load and individual rifle. What has become our standard load runs right at 2800-2830 fps. While you can run faster this load combo gave extreme velocity spreads of low teens and single digits. Also since we were using a Hodgen “extreme” powder when we tested temperature sensitivity we found it vary less than 30 fps from 20-90 degrees. No other combo we tested came close to this kind of consistency. From my position I will gladly give up 100 fps (or less) for this kind of performance.

Our next refinement was to come up with more robust platforms for military applications. We built and tested based on a Remington 700, Sako extractor w/ dual ejectors, a Sako styled bolt release, a Mauser styled bolt release and blade ejector, a controlled round feed, an M16 extractor and a few others. For extreme use applications the Mauser styled bolt release/blade ejector and the M16 extractor made for the most robust combo.

We developed and launched a line of muzzlebrakes based on testing of multiple designs that took us over 2 years R&D time. You can from a good position watch your bullet strike at almost any distance past 500-600 yards with your rifle scope. This makes spotting your own shot possible.

We have built over 60 338 Edge’s in different configurations at this point, 700 repeaters, 700 detachable box setups, 700 solid bottom single shots, 700 light weights, and customs actions BAT, Lawton, Nesika, etc. Most have been in similar configurations for long range hunting. Most wear the Leupold MK4 or Nightforce NXS optics and weighed in around 14-15.5 lbs. Our main focus lately has been to develop a shorter lighter long range hunting version of the “Edge” and we hope to have completed this project and be testing by fall of 2008.


Also; .338 Edge - Wikipedia, the free encyclopedia


I'm not pandering for S.C or the .338 Edge cartridge, I've only met S.C on two occasions and never fired the .338 Edge in any rifle.


Just asking.

Re: 338 edge?

This round was developed years before S.C. put it on a tactical format and named it...Ask LTLR who had the first .338/300 guarentee it wasn't S.C. Besides the article you read was written by S.C. LOL LOL Ask several competent gunsmiths they'll tell you this cartridge has been around a while...

Re: 338 edge?

sniper2,
Very interesting... I for one was told; {not by Shawn} but by a few of the fellow shooters that he {Shawn} has shot with, that this was a ground up idea and cartridge.. Although I would agree with you, it's pretty hard to find a cartridge in the past 30 years that wasn't wildcatted by another 20 years previously to the last 30 years. Again I thank you for your information on the subject.... sounds like you have quite an extensive back ground and expertise in the subject matter here.
Cheer's.

Re: 338 edge?

It says right in the commentary by Shawn that he wasn't the first one to do it. He just gave it the name.

The best thing to do with the Accustock is to ditch the stock and recoil lug. Replace them with something better.

Re: 338 edge?

I'm not taking anyone side on this interesting discussion, but..... The first sentence say's; "I developed and named the 338 Edge in 2001" which is referring to the cartridge being discussed, not some other wildcat in .338 caliber.

The second sentence say's: “Now I am sure I was not the first person to neck up the 300 Ultra (RUM) case to .338”.
Which is referring to 338/300 RUM…. and from what I understand the; .338 Edge and the .338/300 RUM are not the same, very close but not the same’…, true or not?

So is this a play on words? Or is the .338 Edge really just a necked up .338/300 RUM wildcats and/or the Remington cartridge .338 RUM....? Which was tried, I’m sure by many others the day the brass was available, when Remington put it into their stable.

Fact is; I have a good Canadian friend, that designed and brought out the .300 Imperial Magnum, which I’m sure later became Remington’s .300 RUM…. the .300 Imperial Magnum started life many, many years ago {as I remember} as the .311 Canadian {Imperial} Magnum’…, {not to be confused with the .300 Mashburn Imperial Canadian based on the .300 H&H case} and then .300 Imperial Magnum {which is pretty close, near identical to the RUM} was also wildcatted into a .338 Imperial Magnum….. The gentleman and friend was Ret RCMP Officer Aubrey White of Osoyoos Canada, one of the great cartridge design guy’s’…, who was way ahead of his time; in reference to long range hunting and sniper cartridges.

Just trying to get the facts in line.

Re: 338 edge?

Yes I have extensive loading data with most everything from 160gr to 300gr bullets as do several of my friends.I believe S.C. said that the 338 edge is in fact a .300 rum necked to .338
just a simple neck up on the case...My data was compiled in the late 90's and there are more bullets to choose from in .338 at present time..S.C. has made some impressive looking tactical rifles in this chambering.......
