Looked at different tables and yes they are almost identicle in those projectiles, the 300WSM is alittle faster. Sorry if that bothers you.[

Yes, the 300 WSM operates at a higher pressure, and, I have chronyd 300 WSM factory loads they are about 100-150 fps off the advertised velocity, so, you can't always believe what you see. And BTW, the .300 Win Mag loads were usually right on the money, or prtty close.
