.338 Win Mag loads

Now I know that a whole lot you all are shooting .338 of different types but, what about the straight .338 Win Mag? What bullets and velocity are you getting along with range [img]images/icons/confused.gif[/img] . DC you seem to be very curious and inquisitive so I'm hoping that you might have some insight [img]images/icons/wink.gif[/img] . Driving to the target.

    my .338 win mag will shoot under 3 inches for 5 shots at 500 yards.using the sierra accuracy load of imr 4350 67.4 grains with a sierra 250 sbt.i have other loads that shoot great at well.i dont have the col with me right now but the bullets are just oof of the lands.deburr the flash whole and uniform the primer pockets.do not turn the necks.if you have a ball mike check to see that the necks are not way off..338 shoots all i have tried great the 200 225 and 250 also 275.if your still looking for some loads to try let me know the lyman accuracy loads and the serria work great if you need a starting place,thanks,keith

    imr 4350 72 grains gave me 2800 in my m70 with a sierra 250 sbt but that load came from a lyman book and is very hot very hot.still it was accurate.dont use r-p cases the primer pockets will get lose real quick.w-w cases is the only way to go with hot loads.the win mod 70 with a boss is one of the most accurate guns i ever shot.i have a mcbross now its mcmillan brothers 50bmg it better out shoot my winchester have not shot it at long range yet.try h 4831sc powder goes through a measure and is a slow burner works great,thanks,keith

    winchester-western brass. I am having good luck with both remington and winchetser brass in mine. The new Barnes 185 grain ttsx makes the 338 winchester shine with a flat trajectory and killing power. It may be worth trying for some 338 winchester shooters. I am having good success with it.

    Hi there, I was "surfing" and came across this interesting site - well, for me anyway. I use a ruger M77 which has been worked on a bit (boss, trigger job, etc). It performs reliably on large antelope, wildebeest, etc out to 400m using any factory mor close to factory load with bullet weights between 200 and 215gr. Zeroed at 200m bullet drop is negligible at 300 and easily compensated for out to about 400 (no sniper scope required) and penetration and impact at those ranges is still more than adequate. With a bit more practice and decent conditions (or with a decent adjustable scope) I would think it would also be fine to 500, but havent tried it.

    Re: .338 Win Mag loads

    I almost gave up on the accuracy of a 338 win mag. after over a 10 months of range time and all different combinations...

    ..and then ... almost a year later I tried a different powder...
    338 Win Mag
    225gr Nosler Accubond
    Winchester Brass
    Federal 215 magnum primers

    Here is what made the monster difference
    H4831 sc powder - less than 3/4" consisitent groups at 200 yards
    2785 FPS MZV - 73.4 gr (remember this is for my rifle, not yours)
    .033 off my lands

    I loaded 60 rounds with my recipe
    proven 4 times at the range at 200 yards. (3 out of 4 3 shot groups under .625.
    I am saving the rest of hunting

    BTW: this is a Weatherby Vanguard Serie 1 - a 489.00 rifle....

    Bottom line: test with different powders and seating depths.
