Rechamber 300 RUM

[Wedgy]

If it's an internal mag go with the Wyatt's 3.83" or 4" box

CFE-12 Kit - Wyatt's Outdoors

This box is a center feed design which allows a longer cartridge overall length than factory. The benefit of the center feed design, is that the magazine box lips control the feed cycle as opposed to the receiver rails. This box comes as a kit including he follower and spring. COAL allowed is...

In all honesty the 300 Rum is a Great Cartridge, you can run the 150 gr for let's say Whitetail, 180 gr , 200 gr, 210 gr 215 , 220 gr , 230gr all can be used on Mule deer , Elk ,Moose ect.
All in the 1/10 twist barrel ,

I do have a 26" Carbon 1/9 twist barrel that is pushing the 245 gr bergers @ 3010 ft.per.sec. no critters with that one just yet !
Set up right the 300 Rum is great Round !

Hard to go wrong with Rum ! It taste great and knocks the Critters down !

I too am a lefty. Do you know what length of mag you are using? I would have to change stocks if I needed to go with any longer bottom metal

I went with the 3.825" version. Next time I will do the 4.000" version.

What bullets are you guys running into length issues with the 3.825"?

 

[Buttermilk]

Berger 215 HT in my chamber are right at 3.895" oal. That puts them just over my 3.825" mag box. However, I can load one in chamber and one in the magazine as the bullet tip sits just above the box at the front.

That's why I will do a 4.000" box next time.

Berger 210 VLDH bullets sit just fine in the 3.825" box as they have a shorter nose.

I've got an R700 chambered in 300RUM that is currently with the gunsmith getting a few things worked on. If it isn't a shooter any thoughts on what to rebarrel it to? Or would you keep as a 300RUM I bought it used and have not shot it yet.

Keep it RUM unless you're loading beyond mag length with heavy for caliber bullets.
In that case I'd recommend a 30 nosler custom throated, it'll kill a 300 prc improved.

What dies are you guys liking most for 300RUM reloading?

 

[Buttermilk]

I use both RCBS & Hornady standard 2-die set. Nothing special. Both work quite well. I like the Hornady seater with the addition of the micrometer seater stem as well the Hornady seater stem for the longer nosed bullets.

 

[K.E.C.]

Redding Premium and Hornady Match.
The bushings dies I can use for the other Rums.

 

[MagnumManiac]

My RUM with 10" twist in a 26" barrel loves the Barnes 180g TTSX or the Nosler 200g Accubond or Nosler 210g ABLR. Haven't tried anything heavier to date, I hate Hornady products, so not going there.
I would keep your RUM, I was impressed with it straight away and I am a die hard fan of the 300WM, I own 5 of them!

Cheers.

If you go with the wyatt's box, do the 4" CFE-9. I'm rocking a mostly stock Remington 700 sps, factory chamber. Running 3.96" in the mag, .045 off the lands.

I use the Redding bushing dies. Whatever dies you go with, get a micrometer seating stem.

Probably rebarrel after next season, 9 twist.

Definitely gets the attention of the prs guys shooting 6BR in a 18-20 lb rifle when you whack that 4" gong at 500 plus yards with a 215. Lol
