Mark, I took no offence. Im just saying I think the rum has a ton of potential, because I have seen it. Lapua brass is absolutely better but I have had great luck with the remington stuff (usually I hate remington brass) I have 8 reloads in mine so far.
Mike, You've shot the 375 RUM and I haven't so you know it better. The OP said he was interested in an ELR rifle which to me means well beyond 1K, like maybe out to a mile or 2000 yds. When I think of a 375 RUM, I'm thinking more of a safari or Alaskan brown bear gun than an ELR rifle.

Have you shot the 350 SMK's? What COAL and velocity? If the 375 AX can get 2900 fps with a 350 SMK, I'm guessing the 375 RUM will get about 2700 fps? If so, that bullet could get to 2K just before going transonic and and about 1K @ 1800 fps @ about 4000' elevation.

How's your rifle set up? 3.99" extended mag box?

The 375 just isn't that popular of a cartridge in the LR world and most are going with something like a 375 CT, especially when shooting the larger bullets.

Playing around with a ballistic calculator it seems that the 338 Edge with a 300 gr has a slight advantage over the 375 at extended ranges

Yes I have the 3.99 mag I have only shot the 270tsx, not what you would call a LR bullet by any means but It will hold a half moa as far as I have shot it which is 1100 yards. the 270TSX at 3200 fps has surprised me its an amazing thing and the sheer diameter makes for some pretty intense death. This is why I think having it loaded with a 350 CE or similar itll make it a prety legitimate ELR round. its no Cheytac BUT it puts out some amazing numbers. I am all for anything 375 diameter, the lapua version would be sweet. However im apprehensive to say its a ton better based on my own Lapua. I love my lapua and it shoots great but performance is so similar to the 338 rum and the 338 edge I find it hard to believe the extra expense of the 338LM-375 would be worth the very slight gain in performance and the ability to use better brass. If I had it to do over I would build a 338 RUM over my Lapua just because it would have saved me a lot of money and a good chance the end result would have been the same. If money and time were no issue id scrap them both and build a Cheytac

Oh it definitely does. My 300 RUM will send a 230 Hybrid about 250 yds farther than the 375 350 SMK @ 2700 fps

Re: 375 rum custom build options/ideas??

Well I was shooting for elr but I figured you could get some more horsepower out of a longer tube but.. I guess that not the case.

375 rum is very effective past 1000 yards without a doubt and that pushing 270gr barnes triple shock.

A possible reason you think Africa when you here 375 rum is because there isn't many high bc. Pills out there. I've called over to Berger on many different occasions inquiring about a .375 cal line and they say we are swamped right now with orders of bullets we do have out, but as soon as we catch up there is a very good possibility we will be working on something.

In my opinion a 270gr Berger would be just the ticket for the 375 rum
