    I'd say that performance is similar in the 300 grain Sierra bullet class. I've had custom rifles in both chamberings and other than brass life they're it's not worth discussing the balistic differences.

    338 Lapua brass is $130 at Sinclair or Brunos Shooters Supply both if you buy 100 rounds. [img]images/icons/wink.gif[/img]

    My buddies factory 26" bbl Rem 700 338 RUM is pushing 250gr Sierra GK's at barely over 2800 and still getting slight pressure signs with RL25. I have the load data filed if you want it. His were seated to load in the mag at 3.65" OAL.

    The 338 Lapua is superior with its better brass, also it can be improved quite easily too. [img]images/icons/smile.gif[/img]

    Get a 30" or longer bbl if using either, that would be my recommendation.

    While not my first choice for reloading supplies, Cabelas has 338 RUM brass for $45.99 / 100. Does anyone other than Remington make RUM / SAUM brass?

    QH,
    you can get Federal brass for them BUT, you have to buy loaded Federal ammo to get the stuff... not sold in bulk anywhere. If Federal ever makes it in the High Energy version, I'd get that stuff for sure.

    I easily got 200 fps faster reloads in the HE brass than their standard stuff in my 338WM. 250 Barnes X bullets at 3050 fps vs. 2800 in the other stuff... with the same load. Remington and Winchester were all the same too.

    I lost primer pockets in three to four loadings but other than flattened primers there were no other psi signs at all. I'm sure the load was in the low to mid 70k psi range though.

    Both 338wm's I had would group under .7 moa with those top loads too, my buddies still does. I jumped up the the Ruger 416WBY because I knew I was pushing the pressure and still wanted the same performance with a little more safety margin though.

    Hey avengeusa if you only want a 338 cal 250gr to go 2900-3200 then check out the 338 Excaliber [img]images/icons/cool.gif[/img]
