[QUOTE="Long Time Long Ranger, post: 345241, member: 505"] I did some research to see what this thing is. Basically a shortenned 338 lapua improved. I can see some advantages to it. When the 338 lapua came out several of us around the country were in continuous contact trying various improvements to try and get 338-378 wby velocities out of it in a more efficient case. That long sloping case was perfect for improving and reminded us of the old 375 H&H case that became the basis for about every magnum out there. None of us could quite get 338-378 velocities out of it but were close and found that it offered several benefits over the 338-378. One of those was that it shined with winchester WMR powder. It is basically a ball type H-4831. A much faster powder than most big 338's needed. This allowed us to build 338 lapua imp's on a 26" barrel and keep the weight under 10 pounds scoped out while retaining top velocity virtually equal to the other big 338's that needed 30" barrels and a lot of slow moving powder. Now we had a light carry gun capable of putting a whomping on big elk at extreme ranges. With that in mind I think the 338 Norma will react the same way and could possibly become the best big 338 out there to build a light carry gun with a 26" barrel capable of extreme long range. I think it could be similar to the 338 ultramag vs the 338-300 ultramag in the fact that with the slightly shorter 338 ultramag case the powder capacity and velocity with the 300 smk is virtually identical to the 338-300 ultramag because you can load the bullet further out in the 338 ultramag with the same length magazine. I bet the 338 norma would be similar to the 338 lapua because of this. Like I said, I have never fired one and am purely speculating using things I learned with similar cartridges. But I think that short fat case will shine with a faster burning powder creating what I am looking for which is the best big 338 in a 26" barrel under 10 pounds ready to hunt. I think it is worth a try and I am going to do one when I get my house finished. The lathe is already in the garage but my wife said I can't use it until I finish the house. [/QUOTE]
