    7mm Blaser Magnum info

    The 7mm Blaser Mag seems to be growing in popularity so I figure it deserves its own thread.

    Here's some of the info I've collated which might be useful to those that have, or are considering the case.

    Built a few now, goes well enough to scare the pants off a 28 Nosler with 10 grains less powder

    The latest one, https://www.nzhuntingandshooting.co....-magnum-42702/

    I have 7 Blaser Mag & 6.5-7 Blaser reamers & soon a 300 Blaser mag reamer

    I'm happy to build a 7 Blaser Mag on a T3 Tikka, won't build a 28 Nosler on one though....

    Some of your data is aways off, 72.6 of 2225 with a 180 will ensure you won't need a primer tool to put a primer in a case, or at least nail polish etc to keep it in there....I couldn't/wouldn't run that even with a longer COAL

    @Kiwi Greg what sort of barrel life would you expect with a 6.5-7 Blaser & what speed from say a 140gn pill?
    Shut up, get out & start pushing!

    I can't imagine it would be great but at least 5-700 maybe if looked after nicely, ie hunting rifle, not gong/Goat/Varmint rifle.

    IIRC 140-43s easily past 3200fps would have to check the data

    Yep just like a big 7mm, if you get it all organised inside 200 rounds which is quite doable there is still 3-500 rounds for hunting which is tons, at least 5-10+ years worth of hunting.

    If its less you have spent tons on Ammo, diesel & choppers so can easily afford the eleven hundred to twelve hundred ish to replace the barrel

    Hey Greg,

    Your thoughts on comparing a 6.5x68 RWS with the the 300 Blaser, just looking a basic dimensions they look very similar, even their H2O capacity.
    I have a 300 Blaser and love it, and currently building a 6.5x68RWS so find this thread interesting.
    Both are hunting rifles.

    Cheers
