338 Edge and RUM reamer options available to me. Help me choose

[OH58DViper]

I have a 28 Nos I can't get to shoot so it's getting sent off to become a 338 RUM or Edge. Going with a 28" benchmark med Palma 1:9.5 on a Defiance action in an EH1. The reamers my smith has on hand are a standard 338 RUM reamer and a zero free bore Edge reamer. My current Mag box is 3.700 and I want to run 250's around 3000 fps.

So my questions are

Which reamer?

Would you get a longer Mag box and what's involved in that?

Is 3000 fps possible with a 3.700 COAL restriction?

Thanks in advance!

A couple of questions.
Is the same smith who built the 28 nosler building the new one?
When you say it won't shoot explain please?
Do you have a supply of 338 rum brass?

Bought the gun used so it won't be the same smith

I couldnt get it to group better than 1 minute. I tried tons of different bullets, powders, primers, scope options, and shooters.... could get any consistency. Possible it was damaged during shipping IDK I came home from deployment and it was the only one of my rigs I couldn't get consistent 1/2 or better results from.

I will buy it off gun broker if necessary. I hate feeding poachers but it is what it is.

Are you dead set on the rum case?
I don't know what you have in mind for build components on the rifle but I would suggest looking into the 338 Norma mag case. It takes a lapua sized bolt face and a different mag setup but is a better cartridge than the rum case.
Just a suggestion

Yeah I'm kinda stuck on the two afore mentioned cartridges, have a standard Mag bolt face and don't really want to change bolts.

I have both. I shoot the Edge more.

28" barrel and 250grain or less, yes you could make 3000fps. Your brass may suffer.

If you are after 3000fps with 300grain, I don't think you will find that at 3.700 COAL.

My choice would be the 338 RUM. If you use the edge length cartridge with a 3.700" length magazine, you may have to seat some bullets with the front of the bearing surface inside the case neck. I think that is an undesirable condition.

My magazine choice would be a Wyatt center feed #CFE-12 but I don't think it is necessary for what you are wanting to do.

I think a 250 gr bullet at 3000 fps from a 28" is a reasonable expectation. Nosler and Hodgdon both show several 250 gr 338 RUM loads at over 2900 fps. Those are at a 3.600" OAL and with 24" and 26" barrels.
