338 Rum to the Max !

[Rum Man]

I'm looking for info and or experiences with taking the 338 Rum to its max ability.

Should I get a throat reamer ?
Should I sent the barrel out to Shawn Carlock to get the +P treatment?
Is there a special reamer out there ?
It's a standard cut chamber Rum right now.

Looking for any advice or info !

I have Adg brass, lots of different powders to test /try and going to use the 300 gr bergers as my bullet of choice .

This set up will be my hunting Rig to way out there ! Maybe 1500 yards ??

Defiance Tenacity, prefit Proof 1/9.4 twist 26" barrel . This Rifle will have 125 min. Of Elevation available when it's done!
I dont care about oal !
This will be Single fed !
I already know about the 338 Edge is a touch better so we can let that go for now.

Thanks for all your help !

I think you will benefit from +P throating esp. when your case capacity is not maxed out.

Thanks !
The +P.is heavy on my mind . I have a close friend that had Shawn build him a 338 Edge and is getting Amazing results with Nv570 and 300 gr Otm's . 300 ft.per.sec faster then any Edge I have had.

I run 300eh with N570 in my throated rum. 2810 is 1.5gr below psi. Its a 28" proof 9.4tw made several years back. Its on a Terminus helios that was cut for 4" mag box. A bat action with 1-1/8 tenon may get you to the next node, but it would be HOT. RL33 is another good powder with the 300gr bullets.

 

[Rum Man]

Thanks !
Rl-33 is a powder I haven't tryed yet . I did end up with 2884 ft.per.sec in a 30" Carbon barreled 338 Rum with H-1000.
This one is a 1/9.4 26" Proof . If I can get it close to 3000 ft.per.sec or more I will be happy !
I'm going to talk to Shawn about his +p and then make a plan so far.
Thanks !

What exactly does the +P treatment consist of?
My 338 RUM is on a 700 action with a #5 27" Krieger. With Nosler brass, 250 AB and Retumbo I'm get 3120 fps and 2.0" groups at 800 yds.
Tell me more...

Why not just chamber it in the 338 edge? 90 thousandths of additional powder column is a great start.
LRT has the fastest velocities for a 300 berger in my edge....over 100 grains. It's pretty accurate too, but fairly dirty.
I use N570 for the 262 gr hammer and
H1000 for the 300 berger

I put these two rifles together years back .
338 Rum 30" Benchmark carbon 1/10 twist. Both built on Remington action's.
338 Edge 30" Proof Carbon .
Did load work with h'1000 and 300 gr bergers. No other powder at the time .

They ended up at 2884 and 2883 ft.per.sec. So I proved to my self that the 338's are so close to each other that the Rum would be a great choice if your trying to go the cheapest route , if you had a 300 Rum you could just resize the brass to the Edge . Dies are alot different in price also. Rum being alot cheaper and less steps to reload .

I'm sure I will always have a few of both of them around . Just my favorites I guess.

The +p treatment eats out enough throat that I wouldn't do it period. If you want your throat half shot out, go shoot it out. rl33 is also a bit slow burning and bulky for a 338rum. I'm at a full case with my 300rums and 225's using rl33. I'd think a slow burning rather dense powder like lrt might be the ticket here. The new sta-ball hd? powder that's supposed to be ball/ retumbo might also be useful to you.
