    any proof one is better than the other in 600/1000 br ?

    is it just the smaller case has less heat in a 10 shot string >
    easier to shoot in a 10 shot string ?

    how big of an advantage (if any ?) of shooting a 250 in a 300 wm over a 215 in 300 wsm ?

    just asking no opinion nor experience in this discussion

    Build one of each and try them! I'll stick with the WSM.

    well joe,
    I am trying to avoid that cost...retired is also limited funds.
    my guess was wsm grew based on less recoil/powder same(close) bullets weigths.

    I have used both and for a number of reasons the WSM is better, one of which is the accuracy. Barrel life, wider node is a couple more..

    Cartridge efficiency is why the 300-WSM will inherently out preform a 300-WinMag to accuracy.
    As repeatedly seen in many calibers and cartridges, any time a cartridge can achieve similar velocity with less powder (efficiency) it inherently will be more accurate, have less recoil, less barrel heat and less barrel wear, simply because burning less powder to achieve a similar performance level.

    A couple other example's of cartridge efficiency gains:
    - 6BR verses .243-Win
    - 6.5x47L verses 260-Rem

    First you will have to define proof, then deal with a bunch of scientists whos definition differs from yours ;). Bottom line is it takes a VERY good shooter to tell the difference between cartridges. My advice is to find someone who has set more than one agg record with more than one barrel with the wsm or wm, have them shoot a few barrels of the other and see what they say. If you cant shoot an agg record I dont think you can have an opinion on the full accuracy potential of a cartridge.

    You can just observe good shooter's and see this, I don't have to be a farmer to know where milk comes from.

    Exactly What I said. Those shooters can tell you which is better but they have to have vast experience with both. Just beware of those who have only shot one and have attachment to it. Then all you will get is an opinion.

    Id pick the wsm over the wm for the shoulder vs. belt alone.

    I believe Matt Kline has proven the 300 WSM is better. - The 300 Win Mag. doesn't currently hold any 600 or 1000 yard Benchrest records.
    And when more good brass choices in WSM come it will only get even better IMO.

    Note to Norma 300-WSM brass: a fellow constituent of mine emailed Norma the other day about USA availability. They replied back stating that the next shipments should be in the USA in January 2020.

    Much better accuracy, easier to tune, brass will last longer, no belt and the throat won't move compared to a 300 Win Mag. I can shoot 1000 rounds and the throat usually only moves .003 to .005. You definitely won't say that about a 300 Win Mag. How many 300 Win Mags are shooting long range BR verses a 300 WSM? They are shooting the WSM for a reason. Matt

    My comment was about the brass availability issue.
    Good luck with your Hornady brass, lol.
    I wish more quality manufacturers made WSM brass.

    300 WM use to be @ 1k but with the WSM and better cartridges it has faded out..

    Trust me, LR Benchrest shooters Are Not Shooting Hornady Brass. (In the 300 WSM or many others for that matter).

    No good brass available for WSM. Joe Salt, what are you using?

    For brass availability I'm considering a 300 SAUM. Norma brass available and necked up ADG 7 SAUM.
