.338 RUM vs. .338 EDGE

Why would I want to go with a .338 Edge over a .338 RUM? Is there a lot of difference between the two rounds?

Thanks and sorry if this is an ignorant question.

It is just about 100 fps.

Re: .338 RUM vs. .338 EDGE

I initially wondered the same thing. Until I saw that the Edge is built off the 300 RUM case, which has a little more powder capacity than the 338 RUM case has.

I believe the 338 EDGE has to be handloaded for, whereas the 338 RUM is a factory chambering. Don't know if that matters to you or not?

Performance wise they are the same thing. There is no fps difference between the two. The difference is the trouble of loading the 338-300 RUM wildcat vs over the counter 338 RUM. Much easier to buy 338 RUM and shoot.

If your shooting factory ammo 338rum obviously but I can't even afford factory ammo in standard calibers these days so I have to handload if I want to shoot much and if your handloading anyway then 300 ultra brass is much easier to acquire regularly and has more options. Necking it up is a piece of cake.

I handload. Guess I still dont get the high level of interest in the .338 Edge if the .338 RUM is ballistically its equal. Not looking to pick a fight, just trying to understand which .338 to go with. Thanks!

Re: .338 RUM vs. .338 EDGE

The 338 RUM feeds better through standard magnum actions with long 338 bullets which is why Remington made it slightly shorter. Usually guys buy a longer custom magazine box like the wyatt's for the 338-300 RUM or just shoot it as a single shot. Anytime you go to a wildcat cartridge other little problems usually come up other than just the trouble of necking your brass. The same accuracy loads commonly used shoot well in both. +-92 grains of H-1000. What velocities you get depend on your barrel because there is not enough seperation between these two to overcome individual barrel differences. I tested these two at length on my range when the 338 RUM came out in 2001. I quit doing the 338-300 RUM I had been doing for a few years at that time because there was no improvement in performance and the 338 RUM was over the counter.

Basically the 338 RUM will do anything the 338-300 RUM will do in a hunting situation and it is over the counter. If a guy goes with a custom rig then one with more performance than either of these makes more since to most people in the know. The improved lapua can top these two by up to 150 fps. Then the 338-378 improved stuff and the Excaliber which is also over the counter can give you up to 150 fps beyond the lapua imp. Then always remember you can get a slow 338-378 imp barrel and a fast 338 lapua imp and be shooting the same velocity. Or get a slow 338 lapua imp barrel and be shooting the same numbers as a fast ultramag.

For another guy quite a while back I went over all my old loading notes on all the popular 338's. My 340 Weatherby shoots the 300 SMK 2735 fps with best accuracy load. This is right in there with many lapuas and ultramags. One of my 338-378's has best accuracy at 2940 fps. Only 205 fps difference and these two are on the slow side and fast side of big 338's. So basically if you have your own 1000 yard range and shop right beside it like I did. Then build all kinds of 338's to test side by side. You realize through time and 1000's of rounds there is just not a lot of difference performance wise between all of them. Combine a fast cartridge with a fast barrel and a slower cartridge with a slow barrel and there can be quite a difference. Reverse that scenario and there may be very little difference. You just never know what velocity range your best accuracy will come in at. Therefore make your choice based on other criteria such as cost, availability, quality of components, time consuming extra details, etc.

Cartridges like the 338 RUM and 338-300 RUM that basically shoot the same numbers anyway are just so close it is irrevalent to judge them by performance. They must be judged with other criteria. All are equally accurate if built right. I kept a couple of the original 338-300 RUM's I did back in the 90's but since the 338 RUM came out in 2001 they have got very little use. All of my hunting and shooting since then have been with the 338 RUM when I used the ultramag case. To me after putting both through the ringer in testing and considering all the factors in my opinion the 338 RUM is the best cartridge. If it wasn't then the 338 RUM's would have been on the shelf for the last ten years instead of the 338-300's.
