195 eldm 300wsm FFFFFFFFFFFF!

Hey guys, I’m pretty much stuck. I’m doing a load dev for a 300wsm using the following components.

Normally brass
Federal215
Reloader 17
195eldm

23”barrel,the guns a proven shooter.

Has anyone played with the 195eldm? I’ve since read some mixed results them, very much on the edge of just tracking down some 178eldx to test and scrapping the 195s. But I’ve got a bunch of them and I’d love to preserver with them. Mag length is limited and making them have to jump a long way which is less than ideal yes, but I’ve tried single feeding them at 20thou off and either side.

Any suggestions or comments on the 195eldm, have you tried them?

Have you tried them yet?

Yep, have put around 65 of them down range. Have found a sweet velocity node but groups are horrible and super inconsistent. Nothing has shot well at all. Barrels not fouled, I’d like to think I’m not spastic behind a rifle too.

That's Jesus telling you to change projectiles.
I assume your twist rate allows an adequate stability value?

Yeah sorry, 10 twist, should have thought it’d be proper stable. I guess there’s a reason the 195s never shone like the 178s and 208s/212s!

Iv found other eldm to like 30 did you try that?

certain rifles don't "like" certain bullet/powder combinations.

I once did a test with one of my rifles trying sierra tmk and hornady eldm... the tmk was consistently sub-moa over pretty much all loads and no poi shift @100m. the eldm only for one particular (very hot) load...
guess which projectile I went with...

another time one powder/projectile would not produce any proper groupings... same bullet with a faster powder... sub 1/3 moa!

does not mean eldms or the powder you are using are bad. they might just not work too well for this particular rifle...

Could try a different powder. I’ve had rifles shoot the same projectile terrible with one powder and great with another.

So the rifle is a proven shooter with some other projectiles but maybe not with those ones.

I would switch.

Plenty of powders to choose from for 300wsm - 2209, 2213SC, SPF, Hyb100V, RL16, N560, IMR4350.

Try some 2209, if it still won't shoot them move on

Didn’t even know they made that weight. Try another powder then look at another projectile.
178s with 2209 seems to work most of the time in Tikka and 2213 with the 208s seems to work well also. The 208 ELDM is bloody amazing further out at lower impact speeds, not that WSM would push them too fast anyhow.

I use 62gr of RL17 pushing 200gr eldx at 2940 out of my 23inch xbolt, could get more fps but with groups around half inch why bother

Now you're talking, the box I brought only states 2810, pretty pedestrian.

@Blackmac is that at xbolt mag length? Ripper load too!

This is why you shouldn't bother:

Edit: Speer show a max of 61.6gr with a 180gr bullet for 2934fps from a 24" barrel. Methinks your load is taking the piss a bit.

Seems ok to me and Hornady are more conservative than the likes of ADI or Alliant data.

I'd actually trust Speer over Hornady in this instance. Particularly with the software also suggesting that it's over-pressure. Hornady aren't always super conservative.

An alternative is the Sierra 195gr TMK. Accurate in both my 308 & 300 Norma. Gunworks normally stock these....& sample packs too I think :thumbsup:

Thanks guys. I’m going to try the 200eldx. Theres actually published data with this projectile and hornady uses it in their precision hunter line so me thinks it’s worth a solid crack!

Hey pommy why would I make this shit up, I've used load for about 7or 8 years and only trying help Nic. You keep playing with your ballistic apps

Hi Nic, away tomorrow morning till Monday PM your number and I'll give you a call when back with COAL etc.

You’ll love this then.

Blackmac, I'm not accusing you of making anything up. I've shared a couple of data points that suggest you've been leaning on it harder than you perhaps realise. McNotty has shared some data points that suggest it's alright... cool... so the water is muddy in this instance.

That Hornady data shared also suggests your recipe is right at or slightly above max. You're getting top velocities with a slightly shorter barrel and 0.8gr less powder.

I tend to side with grt over books.
Especially hornady look at their superformance line jams bolts in a lot of cases it’s fine to run that load but I’d be wary of suggesting it

I’m a little confused. He is using nearly a whole grain under the Hornady book maximum and compared to Alliant powders reloading data, Hornady are very conservative.

Plus 1 for 195 tmk, use these in my 300 win mag, consistently sub moa at the range and great on sika at distance.

My comments based off the psi from the grt clip in their looking at the hornady data it would suggest he’s spot on at right around max velocity for a 24” barrel, powder charge is irrelevant both of my rifles can’t reach book max charge weights but they can reach book max velocity’s

thanks for everyone’s input. I’ve ditched the rl17 for 2213sc and it’s a day and night difference. Groups have shrunk right down and es is sitting at 10 over 5 rounds. That’ll do!test it at 500 to ensure it’s holding true and we’re good to go. Wish I switched over at the start haha

ADI way more cost efficient as well happy days
