    Any of you gents shoot the 180gr. bullets out of your 338 Win. Mag.?
    If so, how do they perform? I'm looking for "longer range" velocity and
    accuracy. Attempting to take large whitetails at over 250 yards and beyond!
    What is the optimum bullet weight for a .338 Win. Mag cal. out a 24" barrel?
    Does anyone have any "special recipes" for reloading this caliber? Thankyou.

    ps. I know this post may sound a bit excessive, but I want to "anchor" them!!!

    Haven't done a whole lot of load development on the 338 mag. but I have used this
    recipe with success on mule deer in Wyoming. 200gr. Combined Tech. Ballistic Tip, Federal Brass, CCI 250 primer and 75 gr. of IMR4831. My OAL was 3.335"
    I was using a Winchester Model 70. Rather mild recoil and deer just dropped. Longest shot was just under 200 yds. I don't think there is such a thing as overkill in basic hunting rifles.

    Just bite the bullet and get a bigger gun. A 50BMG might do the trick!

    had one a long time ago. I seem to remember the 250 grain sierra soft point boat tail bullet was outstanding. oz

    I used the 210 gr. Federal Premium for elk and shots from 350 to 400 yards were very accurate. For bears and moose I used a 250 gr, Nosler partion bullet which was handloaded, would have to find the rest of the particulars. Very good rifle for the far north hunting.

    The S.D. of the 180 in the .338 causes that not to be your favorite choice. They are fast at start but if you are looking for a long range load I would make the 210 gr. my minimum. P.S. I love the .338 and it's versatility.

    The question can not be answered without first knowing the twist rate of your barrel. The faster the twist the heavier the bullet that can be used. HMB

    Not knocking the 338 as I have one, but my favorite for your situation is a 7MM mag with a 154 grain Hornaday. Very accurate, good balistic coaficient and half the recoil of the 338.

    Most 338's have a 1-10" twist, so will be good to go with about any bullet weight. I was thinking along the lines of 210 gr. They don't have a laser beam trajectory, but do hit hard and anchor game. They hit hard at the buttplate as well.

    If you are hunting whitetail at "250 yds and beyond", nothing is wrong with a 7 Mag. If the standard remmie is not fast enough for you, look at the Ultra Mag. With the right bullets, this one IS a laser beam, and will kick less than the 338.

    It will push a 150 gr bullet at 3300+ fps, and when sighted in at 250, has less than a foot of drop at 400 yds. The 338 has twice the drop with the same setup. At 400 yards, the Biggest Seven has MORE ENERGY than the 338. Something to think about. The 338 can best be described as a big 30/06, with about the same trajectory. The Ultra Mag is FLAT AND POWERFUL.

    Why not try getting closer? There is such a thing as being out of range and pass the shot rather than risk a cripple getting away.

    Dear Southbend

    THANK YOU. I have sold all my flat shooting magnums and have a 308 and 30/06 for big game rifles. I sight them in using the rule of three and feel good about shots to 300 yards. If I cannot get closer, then that critter will live another day!

    OTOH, if a shooter has a long range rifle, and can properly shoot, feed and care for it, then I don't have a problem with the 400+ yard shots.

    As REAL SPORTSMEN know, such shooters are rare creatures.

    The 300 Ultra HURTS to shoot. The 7 Ultra is not quite as bad. Another reason I went to 308 and 30/06. ;^)

    Also, military and former military rounds have components and loads out the wazoo and can be found cheap. Nothing cheap about shooting a magnum big game rifle.

    Map,

    I used 185 barnes TSX this year in my Mdl.70 26'' bbl .338 to anchor a large lead cow elk with one shot at 250 yds or so opening morning of the 3rd. season in Colorado. Broke off-side shoulder and went into the hillside. Funny thing was the meat wasn't as bloodshot as I had expected. I used a max load w/R19 and is moa at 100yds.

    I've never seen ANY deer that remotely required .338" to "anchor it". IF the .338 WM is Your only rifle I'd choose the 210 NP or the 200 gr BT and come up with an accurate load towards the high velocity end of the load data.

    Then shoot that load at whatever distances You feel You will encounter. Out to 250 yds I've found most drop data to be reasonably accurate. Beyond 300 yds You may be surprised. PLACEMENT is the key no matter what the range, game or bullet.

    I've killed a lot of deer and elk as well as some African plains game with a .280 Rem pushing a 150 gr NP at 3000 fps. I do not shoot beyond 400 yds. I'm aware of the true drop figures out to 400 yds. I've NEVER had ANY drama on ANY game with a properly placed 150 Nosler Partition. I could say the same for a .308" 180 NP at 2950 as well as a 225 gr .338" at a sedate 2500 fps from my .338-06. You don't need 3000+ fps to take game within reasonable (under 400 yds) distances.

    I use the 250 on elk and 225 as well. The 225 is a better choice for deer. It has less felt recoil than a 300 UM in like weight rifles. .338 parks them if hit in a lethal location.
