I do not have experience with that brand and load of .338 LM ammo, but you question is a bad one. I suspect that you meant to ask what factory .338 LM ammo have others found to work best for them in your (insert brand of rifle, action, barrel length) rifle and based upon those responses, make a decision as to what you will try in yours.

Barrels will vary as to which load they prefer and if you are only using factory ammo, your best bet is to buy a box of each of a few types and brands and try them in your rifle.

Also, it will help to narrow your responses if we knew what your intent was for your rifle. General plinking, match level performance at long range, hunting, ELR shooting? That way you can get input on the best bullets for your application at the same time.

For what it’s worth and without additional information, generally Lapua and Prime make high quality ammo that performs well. Some people have good luck for their use with the lower cost brands.

Personally, I load Hornady 285g bullets over 91.4g H1000 and get excellent repeatable results out to 1200 yards or so. After that, I like flatlines loaded to 2950 FPS for longer distances. Good luck with your journey.

You are right . I own a sako trg 42 338 LM. Trying to get the best performance in long range target shooting. I think this helps narrowing down the answers

Hijacking in progress...Lash, specs on rifle please. I’ve given up on Retumbo for two reasons, it never shot the 285’s well out of my barrel no matter what I tried and it’s generally impossible to find. H1000 I have pounds of since my 300WM loves it; think I’ll work up a load with that and see what happens. Thanks!

Those Sakos are nice.

The rifle is unimpressive, just a stock Savage 110 LRP that I bedded and cut in a cheek piece. The bedding job made all of the difference. Lapua brass with the 285 BTHP seated 0.020” off the lands shoots lights out with single digit SDs at a mild 2780 FPS.

To not further derail the OPs thread, PM me with any further questions. (y)

I also have a 42, mine eats Berger 300 grain OTM, hated hornady bullets. Can hold a pretty damn tight pattern at 1850 yards. Give the Berger factory ammo a try maybe.

Retail 338LM ammunition. No tweaking, no customization. Expensive venture to possibly find just "acceptable" results.

There are just some calibers that are meant to be reloaded for. This is one of them. If I had to go retail though, I'd probably look at Berger's offerings - or factory Lapua.

I have shot my trg 42 enough to shoot out the factory barrel. I never shot factory through it beyond zero and brake in. With hand loads it shot the scenar bullets well and shot the berger 300 otm exceptionally well. The Hornady 285 eldm didn’t seem to like it as much. Try Lapua factory ammo with either 250 or 300gr scenars or berger 300 otm factory ammo first. Either option will yield Lapua brass which you can use to reload if you decide to go that route. Expect 10+ reloads from that brass when prepped correctly every time.

below is a group with my hand loaded 300 berger otm ammo. Typically performed a ragged hole at 100 and touching at 200.2FB04886-38D0-40D2-AA0C-FA9775F43603.png

The only factory ammo I've had any experience with have been Hornady Match 285 grain, one lot with AMAX the other with ELD-M, and Federal GMM with the Sierra 300 grain Matchking BTHP.

Both Hornady loads were similar in accuracy with the best group .333 MOA and several other groups in the 4's. This in two rifles with two shooters, neither in any danger of winning a match. The FGMM didn't quite keep up.

YMMV, but if I didn't reload, I'd grab a couple boxes of the Hornady.

My Barrett loves the 285 eldm loads. Shoots in the .3s as well.

I should add that if you want to keep your options open to reload down the road, Hornady brass has a reputation for being soft brass and won't hold up to as many reloads as some other brands of brass. The FGMM has a reputation for being tougher brass but even after the first firing, primer pockets were much looser than my Lapua after seven firings. The Hornady was still pretty tight after two firings.

Keep that in mind even if you never reload because that once fired brass has value. Selling once fired brass can bring your cost down by ~$1 a round. You might consider trying a pricier brand like Lapua because if your rifle likes that best, the cost could even out after selling the once fired brass with the premium it would bring.

Oh, and that .333 MOA from above was at 400 yards.

Not to be too much of a dick, but the original question should have used “precise” where ”accurate” was utilized. Accuracy is a mechanical function. :-]]
