Well, I had decided to push it to it's max with the 250gr Nosler Partion, and that I did. I couldn't believe my eyes when I seen the chrono, which was 12 feet from the muzzle.

Ruger M77 MkII Stainless .338 Win Mag 24" Barrel

High Velocity - 2890
Low Velocity - 2842
Average Vel - 2871

5 shot group was 1.5", so nothing great there, but hey, I was going for speed right ?

We videoed the whole thing, just incase I had doubters lol

I will not post my load info, as I am well past listed max. But I will say Im getting flattened primers, with no cratering, and bolt lift was just a tad stiffer by the last shot. But it's 90º+ here today.

Wow, that is screaming for sure. Best I can do is about 2780. Yours are into 340Wby speeds. Great shooting but man oh man give us some reports if you are getting loose primer pockets or any other items of pressure. That is great data buddy. I run 225's about that fast. Scotty

Getting 2954 consistently with my 338 WM and nosler 225 accubonds. Chronoed many times. No signs of pressure and shooting just under an inch . Like it! Also a ruger. Hawkeye all weather though.

I'm shooting only slightly faster with 215 grain Sierra GKs. I love the groups I'm shooting though, and it should be more than potent enough for whitetail deer. ;-)

I've loaded some 225 SSTs too, but the groups didn't compare to those of the Sierras.

I have a .338 Win mag in stainless steel, with a 26 inch barrel and I got 2950fps using Nosler Partitions but I mainly shoot the 225 grain Accubond bullet. This is a MAX-LOAD!!!;)

It's been five years since the first post, has that load withstood the test of time? For what it's worth I have the same rifle. Shooting both 225 & 250 Accubonds accuracy falls off when I push them hard, which is unusual for those pills.

Hi there

can someone help with the ballistics of Hornady SST Superformance 225gr, in .338 WM caliber ??

What are the drop figures at 300 to 500m ( 330 to 550 yars) with a muzzle speed of 830m/s ( 2770 ft/s)

That's a fairly light load. If you have a loading manual it should have a ballistics chart in the back section. The best way to find out is shooting at measured distances. Good shooting!

Using a 200 yard zero (+1.7" @ 100 yards), here are some numbers:

300 yards -8", 400 yards -22" and 500 yards -43"

These should be pretty close, but you should always verify.
