[QUOTE="Long Time Long Ranger, post: 510624, member: 505"] I don't have the Norma but have the others and several more. Like Roy said, I can tell you from been there and done that any of your choices will kill anything as far as you can hit it. The difference is product availability and cost, how heavy you want your finished rifle, and what velocity you want to achieve for better drops and less wind drift. About a 100 other things also. Here are the velocities out of a 28-30" barrel over extensive testing with these at my range. The 338-378 Weatherby outperforms the others by about 200 fps and will push the 300 grainers between 3000-3100 fps, 225's between 3400-3500 fps. The lapua is the next fastest by a little over the RUM case primarily because the Lapua brass can be pushed to higher pressures. At the same pressures the Lapua and RUM case are virtually identical and drive the 300 grainers 2750-2850 fps. They push the 225 grain bullets 3200-3300 fps. The norma is a shortenned, improved Lapua but still performs close to these. I laugh at the loading manuals for wby cartridges. They are incredibly underloaded because of liability concerns since custom wby chambers vary so much. The RUM's typically can be built on a lighter rifle because they utilize a standard magnum action which is a little lighter. Remington brass is way cheaper. 338-378 brass is over $60 a box now at Graff's. Lapua brass is also expensive. If you are building a rifle Jamison now makes 338 Excalibur brass carried by Midway and Graff's. The 338 Excalibur has the most powder capacity and is the fastest of any easily available over the counter 338 that will fit in a hunting weight rifle. That is what I would build now if I was doing one. For a light 338 carry rifle I would talk to Devin about the 338 SIN he has been working on.
