[QUOTE="Long Time Long Ranger, post: 338707, member: 505"] To continue that a little the 300 wby case is just really hard to beat when comparing going up to the ultramag and 378 cases. If you look at velocities there is not a lot of difference compared to the barrel life you get. When you go up to 338 caliber the 340 wby off that case is nearly the same as the 338 and 338-300 ultramag in velocity with about 15 grains less powder. With same length barrels my 340 wby shoots the 250 grain bullets at 3050 fps. My 338 and 338-300 ultramags shoot the same bullet 3100 fps. Just not much difference but in 338 caliber the step up may be worth any velocity gain because barrel life in 338's off the ultramag case are very long in contrast to 30 calibers off the ultramag case. I guess bottom line they all kill stuff but for the guy wanting to figure out what is the very best to give him the best of all worlds there would be a lot of debate. Me personally I go with the top velocity out there when hunting seriously to give me the least error in wind prediction which is the toughest thing in long range shooting. Those rifles have accuracy loads worked out, zeroed, and limited zero check and hunting after that. I have plenty other rifles to practice with and just shoot in general. [/QUOTE]
