338 Win Mag Powder choices

[MrClark]

G'day all!

I've been doing some loading and testing for the 338 Win mag.

I've been loading 225gr Hornady Interbonds and using AR2209, I'm getting around 2800 Fps from a 24in Sako 85 hunter stainless.

groups are ok but I think its mostly me and not the rifle causing discrepancies (its like standing behind a donkey)

I'm just thinking is it worth trying some AR2213SC as on the ADI site they say you can get a little more velocity. but is that from a 24 or 26in barrel?

I've tried RL22 as well but it hated it? 2600fps was max velocity with a max charge.

So has anyone here used AR2213SC in their 338 WM?

[MeccaOz]

I just had a look and for a 225gn Projectile it says a smidge under 2800fps and thats from a 24 inch barrel mate, using AR2213SC
.

[MrClark]

ah rogee cheers mate yeah i had a look too.

[Kelix]

Seems like your focus is on velocity, not accuracy.

Have you done a spread of powder charges in your test loads with 2209? There might be a more accurate load that's a little slower than the heaviest charge you're doing there.

2209 is pretty common for 300WM and plenty of people are getting accurate results with it.

Just asking.

[RDobber]

2209 and 2213SC are both popular powders for the 300WM, either could give good results for you.

Depends on the rifle, bullet, blah blah blah. Need to do the testing and find out what works for you as always. If you've done a full load working with 2209 and nothing was promising then I'd try the 2213SC.

What load data are you using by the way? It sounds like you're running some pretty hot loads there...

ADI data says max charge for a 220gr pill is 65gr of AR2209 for 2,622fps.

If you're shooting 225gr pills at 2,800fps you're obviously well above that.

Take this with a grain of salt but I've read ADI test their powders with 22" barrels.

That's not something I've seen direct from ADI, but I've read it on a number of different websites and reviews.

I've tested with both 2209 and 2213 and 2213 got very slow speeds compared to 2209. Accuracy was about the same.

I'm using a Vanguard with a 24 inch barrel.

AR2209 all the way for me for bullets 225g to 250g.

With the 200 grainers don't count out Ar2208 or even Ar2206H. Recently I've been experimenting with 56.5g of 2206 with a 200g Hotcor for a mild pig and deer load. Getting about 2730fps over the chrony.

[Hercl]

Speers only make the Hot-Cor in 200gr, right? Not 225gr - 250gr?

What bullets are you shooting in your heavier loads, bobnob?

[MrClark]

Thanks for all the replies. Sorry, I have been at work so I haven't had time to reply.

I'm happy with the accuracy now with the .338 Win Mag. I found a sweet spot (dunno if its a good idea to publish data) but it's over the ADI max but under the Speer max. Ha ha ha, they're miles apart.

I worked up slowly (very slowly) in 0.2 grain increments of AR2209. Finally accepted that 2,800FPS from a 24in barrel in .338WM is a respectable velocity.

When I'm shooting my best I can get a nice clover leaf at 100m. Good enough for the time being. Plus, the 30-06 loves AR2209 as does the .243 so I'm set.

Thanks everyone.

Best to be careful with these things I suppose.

If what you're using is published by a reputable source (Speers obviously is) then I reckon you're safe posting it as long as you say where the data is from.

Just my 2c. Mods will draw a line I'm sure.

I think we can live with that.

Sorry for the late response Herc.

Using 225g SSTs and 250g Interlocks.

For the 200 Hotcor have settled on 58g of 2206 which shoots real mild and makes about 2800fps. A bit like a heavily juiced 30-06 load which I plan dusting a pig with before long.

[Hercl]

No worries, mate.

Appreciate the reply.

Good luck with the porkers

Mild for a 338 I guess.

I'd probably still end up on the floor

[MrClark]

That's a good idea, (mild load 200gr) especially for practice

[Norton]

Always fun to watch someone who's not yet experienced with their big bore start using it for the first time with full velocity factory loads

I did the same to get more comfortable on my .416 by starting with some gentler loads.

hahaha just wanted to see what i was in for, turns out after about 150 or so rounds and after handling a Kimber in the same cal (Winchester have dropped the ball in regards to availability) im not a Sako fan. gonna cop it for saying that haha but its custom Kimber action time.

Yeah but it's a fun way to travel

If you made it 150 rounds I'd say you've got the big bore bug
