Re: Has anyone thought of making a .338 Norma Improved?
Don't waste your time the 338 norma is an improved design to begin. Its a 338 Lapua case shortened so the 300SMK can be seated out were it belongs and still fit a standard mag box 3.6" loaded OAL. The body taper is at a minimum also. As stated the only thing to improve is the shoulder, and during testing and development of the cartridge it was determined that the best / most consistent results came with the current configuration.
Barrel length will help but the gains are not huge, the cartridege runs great out of a 26" tube. Both of mine shot very tight groups at 2800fps. RSM is the powder of choice for top speed and accuracy. R-22 ran about 2760fps max.
If you are looking for a nice easy to load for cartridge to run a 300 grainer 2750-2800 look no further. If you want 3000FPS improve a 338 lapua, take out the body taper seat the bullet where it belongs and put a shoulder on it and have at it, it will be almost a 1/2" longer than the Norma and require a longer action / set up but will get yu the 3000fps
