With the brass available now I've been thinking about putting my barrel back on. 30" 1:9 throated for 300's
338-375 Ruger Demon

That could be interesting. Schneider is just 60 miles down the road and we know each other so I may have him turn me some barrels. They are twice as high as anyone else's just for a blank but I've never seen anything shoot as well as his barrels.
Nothing wrong with Brux, Bartlien, or Krieger either but each of these is going to be a one of a kind built on Model 70 and/or Montana 1999 actions so if it costs a little more what the heck.

So far so good. I love shooting this cartridge. H4350 has been great for me. With 250gr Berger EH or Accubonds 2952 is about my average fps right now that my barrel has settled in. No pressure signs or issues other than I'm still running the Hornady brass which is good for 3 - 4 firings before primer pockets go. I know Jasnt has had good results with H1000. I haven't loaded with h1000 yet as I'm saving what powder stash I have left for my 300wm. Hopefully in the near future though.

Same brand dies I'm using In 338/375 Ruger. I was surprised they had them in stock. I've had zero issues with them and nothing but great results.

With h1000 I was getting 2830 with 300 gr but my chamber is stretched out .080" longer than the straight neck down of the 338/375 ruger. That gave me about 4% more capacity and then I throated it for 300's to sit just above the doughnut. Load was hard on the norma 8x68 case I used. Might just need to Oder some of that 300prc brass from adg and get it fire formed
I still have one of my 338/375s. I'm shooting an 18" barreled specialty pistol, but my loads track right there with everyone else.
My go-to load for years has been a 250gr SMK and 76.5gr of H4350 at about 2650 from the 18" barrel. The same charge weight of H100v will gain about 75fps of velocity and Reloader 26 gains about the same amount. Neither powder has been as accurate though. The 76.5gr H4350 load isn't very heavy but shoots .5 MOA out to around 700 yards and stays sub MOA out to 1200 yards..
I use the same charge of H4350 with a 260gr Hammer Hunter (2660fps) for hunting.
I shot the 230gr ELDx at 2860fps, but I'll need to dig up my data on which powder that was.
I pushed the 285gr ELDm to 2750fps from the 18" barrel with Reloader 26 but never got the accuracy I wanted.
I've had 4 different barrels of different lengths so far and they've all been easy to tune and came pretty close to matching the 338 RUM when both cases are loaded to similar levels.

I talked Alex into using his 300 prc reamer then go back in and open the neck up to .370. We don't have the actual reamer yet. I have tried the 250 EH quite a few times and just can't get them to shoot from 2900-3000 fps. (74-78) grains of H4350, N555, RL23. Those bullets just seem very fussy. Once we get the actual reamer in, I will give it another shot.

You might try looking for some RWS 8x68 brass if you haven't yet tried it. Really solid brass in my experience.

Curious as to any updates for any of you guys shooting this variant of the 338-375 Ruger.
my Sherman 300-375AI will be on the way in a couple of weeks so the 338-375 is about all I have left to build to have my 375 Ruger variants complete.

I love mine getting ready to try the 230 eldx and see what velocity I get out of them
I'm still very happy with the one I have left. I played with some of the heavier bullets in the 270-285 range, but keep coming back to the 250s as the perfect weight in this case. My gun likes the 250 SMK, but the 250 Berger is a great bullet too. I tried the 230 ELDx, but they never shot as well as the 250 SMK.
H4350 is still my favorite powder in this case, but other powders will give better velocity. I played with RL 26 but wasn't happy with the accuracy. I know another shooter who had great luck with H4831sc.
I still have a 338/375 Ruger reamer if you ever want to borrow one. It's a zero freebore reamer and then I just used a throater to match the bullets I wanted to use in each of the barrels I had chambered.

What twist rate you running? mine has the 1-10 mine loves the 250 berger it's running them 2855 with 7828ssc and great accuracy. 26" #4 brux barrel
The barrel I have left is a 1:9" 3 groove Benchmark.
I'm shooting an 18" specialty pistol, but I get 2685 fps with the 250 SMK and 76.5gr of H4350. I can get closer to 2750 with RL 26 but the accuracy isn't as good. The 230 ELDm shot pretty well at 2830 fps, but not as good as the 250 SMK.
For hunting I use the 260gr HH at 2690 fps.

I've been considering screwing my barrel back on and finishing it up. Got few lbs of h4350 now. Mine 30" 1:9 throated for 300's. Was getting close to lapua speeds. Got 700 though it now
