    Default best bullets for a 338-378 for target shoting

    i have never thought that i would post here,

    I am going to use a 250grains swift A-frame for hunting, I need a bullet that can take a moose on up to 250 meter (long range i Scandinavian :-)) i know what comments are coming about calling 250 meter long range, from my American friends) but also can take a wild boar at 25 meters without breaking up.

    But what bullet will you recommend for "long range" target practice the 24 of April I am for my first time going to a military range, where we can shoot 600 meter. I have never had the possibility to shoot more than 300 meter on shooting range before
    (I will have my .257 and .300 with me as backup)

    here are some bullet i can get quick from local gun

    250 gr Hornady BTHP bc 675
    250gr Lapua HPBT SCENAR bc 675
    250gr Sierra HPBT Match King
    300 gr. Sierra HPBT Match

    it need long paperwork if i have to import from us.

    but what best of thise bullets and what the best i can try to get on long term

    Skipper, I have found that in about any .338 the 300 Sierra Match King shoots well. They don't seem to mind to be a little off the lands, in fact mine in the lapua shoot better at least .060" off the lands. I feel this will work good with the freebore in a 338-378. So if it were me, I would be loading 300 SMK's at mag box length (3.800") over a charge of H-1000 and a CCI 250 primer. Work up your loads at 200 meters. I have seen them take this long to settle in. Then if you like the way they shoot, this could be used for hunting too and anything you shoot with it will be dead. Here is one after penetrating the shoulders of a bull elk at 526 yards.

    Skipper - you might want to check w/Nate (RS2G). I believe he shoots 250 gr Lapua Scenars over H-1000.

    I've not shot the new 300 Bergers. But I do like the 300 grn Lapua Scenars for target/deer/hogs.

    Skipper, My .338 x .378 is normally unpredictable about the loads it likes, but 3 different loads with the 300gr Smkhp were acceptable without any further development. Powders were H-5010 and H-1000. Velocities out of the 27 1/4" barrel were 2750 - 2780 fps with no sign of pressure. I tried 3.8" oal so that I could feed out of the magazine, but it seated the 300gr bullet too deep. The bullet ogive was just inside the neck and it used up too much powder capacity. 3.9" oal and 4"oal both were accurate, but have to be single loaded. Not a problem for target work. My rifle didn't like any load with 250gr Smkhp's.

    This is a truly fine long range cartridge, but shooting prone, it will kick you out of your position if your rifle weighs less than about 15 lbs, or if it doesn't have a good brake on it. Be prepared to take some punishment with the 300gr loads. The lighter bullet loads are very fast, but recoil is light.

    I've never tried the Scenars, but I know they are good bullets. Maybe your rifle will like them. 600 meters is no challenge for this cartridge with any weight bullet. My rifle likes the Factory 225gr Barnes X load, and also a 180gr Nosler ballistic tip (a mild handload at 3479fps). It didn't like the 200gr ballistic tips as much. Only managed 1 moa with them, but at 600 meters will still hammer. I'd say just find any bullet it likes, get a 200 or 300 meter zero, dope it for 600 meters and let fly. It'll print on the target with the 1st round, then it'll help you shoot through bad conditions, and if you have a brake on it, you'll have a firing point all to yourself. Shooters on both sides of you will either move away or get their hats blown off when you fire. Distracts them.

    Enjoy, Tom

    You will really enjoy 600 meter shooting. There's nothing quite like the satisfaction of making medium to long range shots and hitting time after time. It's about the most fun you can have with your clothes on.

    I emailed Barnes for load data on the 265 TTSX and the 285 TSX. They said to use the load data on the Hodgdon/IMR site for the 275 grain bullets. I thought the data using US869 looked interesting enough to find some of it. Bruno's here locally has it in stock so now all I have to do is order some 265 grain TTSXs since I haven't found any locally.

    Skipper, I'd like to know what you decide on and how it works out for you, including the 600 meter results.

    Tom

    On edit: Ken, I tried a load with US 869 and a 200gr AB in my .30 x .378. A very good powder. I like it better than even H-5010. If I ever get back to my .338 x .378, I'm going to try it in it also.

    Skipper, I would think any of those would be great choices. That's really all that's out there. There are the new Barnes offerings of course, but keeping with a HPBT match style bullet (unless you're going with a custom bullet mfg) you've got...

    250 Lapua Scenar
    250 MatchKing
    300 MatchKing
    300 gr. Berger
    250 gr. Hornady Match
    285 gr. Hornady Match

    I might've missed one or two. Do you have any trouble getting particular mfgs. in Scandinavia? Seems like Lapua would be the easiest for you to get and if that's the case, I'd probably go that route. Otherwise, you might try a couple of different choices and see which one your rifle likes best. You probably saw the target that I posted recent using the Hornady 285's. I decided to gve those a try just for the heck of it and I've been supremely impressed. All of my loads with them shot pretty decent, and a couple were exceptional. Beyond that though, all of the ones I mentioned above have good reputations for excellent accuracy. It just depends on which one you have a preference for, which one your gun likes and most importantly which ones you can get!
