In regards to the previous posters, the Norma pre-dates the 338 Win Mag a few years. While the two cartridges are very similar, people forget that energy increases at the square of velocity. You start slinging 250 gr. bullets 100-200 fps faster than another and you have significantly increased the energy figures. On the order of the difference of the 308/30-06. The 338 will usually give 2700 w/250gr.bullet where the Norma is 2800-2850. Recently I've seen the new powders go over 2900 w/250's, but 2850 is all I need or want in a 9 lb rifle. My 23" bbl rifle routinely gives 2825-2860 fps w/250 Partitions and over 3000 fps w/225 Accubonds with no special tricks (ie barrel throating or short chambers). And it is moa accurate. In all fairness, I've seen where the 338WM can give speed approaching 2900 w/250's with the new powders, so time will tell.
Be safe.
