Home Forums Hunting & Shooting Hunting Rifles 300 WSM to 338 RCM - anyone do this?

Not to take away from what you say regarding the 338 RCM being a "338-06 Improved" (it has approx 3.5 gr's more water capacity), but necking 338-06 brass from cheap and available 30-06 brass is the simplest thing in the reloading world... and if you want 338-06 A-Square brass, it's available.

I still am confident the 338 RCM will be in the trash heap of cartridges long-term... heck, even short term.

It will always be in my closet and that is what matters. IF it goes down the road that matters not to me. I'm just glad to have one.

.338 RCM?...hell you will join the ilk of those that have weird obsolete trash pile schit like .284wins and 9,3x64 Brennekes.
and are enjoying them very much...

or go 'extra weird' - neck 300rcm to .338 cause its got 72.7 grains water cap. vs 338 RCM 70.1 grs.

338 RCM baby!! I got enough brass for as long as I'll be around. Shot my deer with one last year.

I am not sure I care so much about whats going to be around for how long. I have two 338 RCM's and have enough enough brass to shoot out at least one of the barrels if not both. if you want off the shelf ammo neither 33806 or 338 RCM would be on my list although there is 338 RCM on the shelves at the two shops I visit regularly, haven't checked for 338-06. If you want off the self ammo I would stick to30.06 or 338wm or if you have to have a short mag 300wsm.


While I like the ballistics of the 338 RCM or 338-06, one of the beauties of the original 338 RCM was the nifty little package Ruger put it in. If I wanted a LW 338RCM I might hunt down one of those and put it in a LW stock.

Anyone have one of those compact 338rcm or 338-06's laying around they want to get rid of?
I don't want anyone's trash heap getting to tall.....but seriously though

Also, if CDNN has the 338rcm, will someone send me a link. I can't find them

I haven't seen them on CNN in some time.
Keep an eye out on gunbroker or post a WTB in the classifieds here.

Sorry that should be CDNN, you can slap me now.

Not to hijack the thread, but I'm looking for a starting...or accurate load using RL15 and a 210 grain bullet. Info seems scarce...just bought one of the 20" barrel rugers. I'm presuming roughly 50-53 grains...but found someone online who was up to 58 grains...seems on the hot side. Any info would be appreciated. Have a bunch of Swift Scirocccos I want to play with.
