[QUOTE="Long Time Long Ranger, post: 338703, member: 505"] My experience with the 300 wsm is that it is very easy to load for and shoots all weight bullets very well in any length barrel we have tried over 24". My personal 300 wsm is a tikka t3 and it shoots anything very accurate. I have tried off the lands and into the lands and all loads are accurate. I like the 300 wsm. With less powder and near the velocity of the big 30's it is hard to beat. My opinion is that barrel life would be very long compared to the big 30's. I don't know how it does it and would not have believed until I worked with it, but the 300 wsm will stay right in there very close to the 300 win mag. Okie2, I think Montana said it very well. Bottom line it is give and take and you have just got to decide which way you want to lean with respect to velocity/barrel life. I have worked with the 30-416 imp, 30-378 wby, 30-338 lapua imp, 300 ultramag and a few more as the really big 30's. The first two get the best velocity and are the hardest on barrels. The 30-338 lapua imp will outperform the 300 ultramag in my tests and both are probably about the same on barrels. That imp lapua design is just a very good efficient design that I have grown to like. I guess because it gets about the best powder/velocity ratio so you would assume the best ratio of barrel life. For factory big 30's with everything considered I like the 300 ultramag and 300 weatherby. The 30-378 wby will outperform these but barrel life is less. So take your pick there of what you really want. The 300 wby is only a 100 fps behind the 300 ultramag but barrel life is way better. I have quite a bit of experience with the 300 wby for 35 years and own five now. I have over 2000 rounds through some and hunting accuracy is still there. I'm sure 1000 yard match shooters retire them before 2000. I guess if you compared all of them as to best velocity vs barrel life the 300 wby is still the top 30 caliber round out there. You can not beat the accuracy of the 300 wby. It's performance in 1000 yard matches for nearly 50 years is a testament to that. But then if you want the top barrel life out there in a magnum velocity rifle the 300 wsm is tops. I don't have enough personal experience with it to wear out a barrel but I have not known of a barrel being shot out. So you see we are basically back to what Montana said. If you want the fastest factory thing out there, reload cost not an issue, barrel life not an issue, it is 30-378 wby. Work up a load, zero and just hunting after that, it should last many years.

The 300 win mag falls between the 300 wsm and 300 wby so not the best of either. Here are some of my average chronographed velocities out of 28" barrels that might help you make a decision now that you are more confused than ever. 200 grain bullet, 30-378 wby 3300 fps, 300 ultramag 3200 fps, 300 wby 3100 fps, 300 wsm 2950 fps. 150 grain bullet, 30-378 wby 3850 fps, 300 ultramag 3750 fps, 300 wby 3575 fps, 300 wsm with 25.5" barrel 3400 fps.
