Thread: 300 win mag

Does anyone have the latest Hornady reloading manual? I’m looking for reloading info on the 200gr ELD-X, using h1000.
I have looked at my other manuals for an idea on starting and max loads based off other 200gr bullets but just wondering what Hornady has o say for their 200gr. As the load data varys a bit with different 200gr bullets.

Also if anyone has any experience with this projectile in 300 win mag, keen to hear from you.

75 grains would be the max you would use h1000

Couldn’t get the 200 to group in mine or a mates rifle.

Cheers kawekakid
Oh that’s not ideal plinky, hopefuly I can get them to shot

Im not into reloading but if you like,try Hornady 180gr SSTs.Groups touching holes and deadly accurate in my xbolt 300wm.Befor this ammo was trying Federal 180gr,on a good day get a 2 inch group,mostly 3 to 5 inchs other wise,bloody useless.

Greetings Blair,
The Hodgdon on line data shows loads for 200 and 208 grain projectiles for both H1000 (AR2217) and Retumbo (AR2225) in the 300 win mag. Retumbo (AR2225) gave the best velocities. My son used AR2217 with the 208 grain Amax in his Sendero. The Amax is very similar to the ELDX so you could use that data. My only concern would be if the rifling twist on your rifle will stabilise the long ELDX. Many 300 Win mags have a 1 in 10 twist which may struggle.
Regards Grandpamac.

@Blair

What rifle do you have?
As the 200gn and upwards ELDs (and previous A-Maxes) are so pointy they need to seated in deep to fit many magazines, ie Saur, Tikka and Sako.
You tend to end up loading them to single feed only. But extracting an unfired one is a right pain in a Sako 75/85.

Cheers for that. It has a 1-10 twist so hopefully will stabilise them.

It’s a tc venture, have just picked it up so will be looking into how long I can seat them and still for the mag.
Hopefully can fit them in the mag and still get good results other wise will have to single feed

What I've done for the 300WM loads for a Sako A7, is to have 180gn SSTs to fit the mag for general hunting within 300-350m. As the A7 has a stupidly short magazine. Even factory 180gn soft points are touching the front of the mag.
Then have the 200gn ELD-X as single feed, seated to 0.25mm off the rifling.
Both loads use the same brass, primers and powder and pretty much shoot to the same POI at 200m. So easy to single feed for longer shots past 400m.

I have a 308 for the closer stuff, looking to use the 300 for 300m plus. So will stick to just one load of possible. What load are you running with the 200gr ELDX?

Quite a mild 75.5gn of ADI 2217. As I've gone for accuracy and brass life over stonking velocity.
Using PPU (Privi/Highland) brass and CCI Magnum primers.

I'm using them. Got them going well in excess of 3000fps but was well over pressure...

Settled on bang on 3000fps which is still kinda hot I think

Sweet I’m going to use h1000 which is ar2217 by a different name.
From what I can find online, looking like load somewhere between 72-77 gr, would that be about right? Obviously watching for pressure.
What speed are you getting with 75.5?

I'm just over 77 from memory would have to check, for 3005fps via labradar.

Factory hornady eldx is 2845 fps (advertised at 2850) so pretty close
