    Is there such a thing? If not, why not?

    Thanks

    I'm looking at the saami specs on the cases of the 300 WM and the 338 WM and they are very close. Why does the 338 have so much more recoil?

    If shooting equal weight bullets do they kick about the same?

    No info on it at Pac-Nor. Did my own research on it and turns out that the 700 action is the only one long enough to hold it.

    Anyone have a comment on the recoil issue?

    Isn't the .338 superior to the .308 as it relates to BC?

    Tom,

    What do you mean? I just use Pac-Nor (and so as http://www.gmdr.com/rcbs/cartlist.htm) as a reference that .338-.300 WM does exist. I'm sure the pros will chime is soon.

    "Is there such a thing? "

    Yeah, there is. It's called the .340 WM.

    After looking up the trajectories, recoil, some BC etc.... I'm going to stick with the 300 WM for my build.

    I want a max 800 yard rifle with manageable recoil. I figure the 300 WM is it.

    Thanks to all that responded.

    It gets within about 100 fps of the 340 wby. Some people would do it to get near the 340 wby with cheap widely available brass. But since the powerfull 338 ultramag came out with cheap brass and performs well on the 700 action just no need for wildcats like that anymore.
