Is he single feeding those or are they mag length?

 

[Rum Man]

Single feeding his Rifle .
If I remember correctly his oal. Is 4.166 but not for sure . The Hammers are long !

Ok his oal length with 395gr Hammers is 4.166 and with the 329gr Hammers its 4.061 .

My buddy bought a 375 and a 338 rum from a site member just a little while back and hasn't shot them yet . I think I'm more excited to try them than he is . After shooting his 416 it got me wanting something bigger than my 300wm and 338 wm so I got a 375ruger not quite the same league as the rum but still a fun big bore with enough punch for anything I could ever hunt.

I got a custom .375 Ruger, 26" barrel, big brake, and 3.825 CIP length action, for the longer bullets, uses RUM Mags, for grins get yourself some of the buffalo bore ammo with the 270 grn barnes bullets. My rifle likes those 0.5 to .75 MOA at a 100 yards.

I have not had time to load develop yet, but have a few loads working up.

I built another 375 RUM, Defiance tenacity action, 32in finished 409modbb bartlein barrel in an 11 to 10 gain twist, beast muzzle brake, hs precision stock (last one I will ever buy) wyatts 3.825" extended box. Built by Mark Penrod of Penrod Precision. Will be running AGM brass and plan to shoot 329 HHs at over 3,000 fps. The bare rifle weighs in at 13.6lb and finishes 56 inches long, now I need to find a case long enough and start working up a load.

Has anyone loaded H1000 or H4350 for 300+ grain bullets? I have a bunch of that in stock.

 

[Mike6158]

I load my .338 Edge with 90gr H1000 and 300gr Bergers or SMK's. That's all I've tried...

 

[Charlielee]

so I'm thinking of moving to a 375 rum to shoot mile+ I don't know a hell of a lot about the cartridge am I pushing **** up hill or can it be done with the right projectile combo etc

Cheers

I have a 375 RUM and have shot some factory 300 gr though it. Standing off-hand while leaning against a pole is the only safe for ones shoulder to fire it. On sand bags is not tolerable, it will hurt the shoulder. I suppose a double bagged led sled could contain the recoil but I doubt the stock could survive it, it is over 5500 lbs recoil, which is like the big African 470's and 500's.
So, I loaded some cartridges down the a .375 H&H recoil with Accurate 5744 using 300gr Sierras which work for me. No sled sled, no muzzle blaster, and a tolerable recoil.
I like them like this.

What brake do you have on the barrel?

I'm guessing "no muzzle blaster" means no brake

 

[crazymonkey]

There's no fun in not putting a break on . You can clear out the range no problem. It will blow everything off the benches to your right or left . Seriously there is way more benefit to a break than the down side of the extra noise. A rifle of that caliber deserves to run full house loads.

This is first accessory I would add .

PAST Super Mag Plus Recoil Pad Shield Ambidextrous

Past Pad

Since I had shoulder surgery 2 weeks ago, the thought of the recoil is making me cringe!

Don't sweat it, I've had three of them and pain is temporary. In all seriousness, best of luck with your recovery!

Yes, they are too disruptive. I can handle the recoil but need more enjoyable practice with it.
