Is the main reason you're going 338 RCM over 338 WSM to fit better into the slightly shorter remington short action?
I have a 338 WSM built on a model 70 short action, and it's just a fun little gun. It is my understanding, which could be wrong, that the WSM case has a bit more case capacity... but you guys are all stating performance levels beyond what I am able to get out of my 338wsm with a 24" barrel. Maybe it's just that I"m using H4350 and not RL17? Or I must be missing something about the capability of the RCM case...
Anyways, this is a cool thread. JE Custom, I would love to see your lightweight 338 RCM. My wsm weighs in a touch under 8 lbs fully outfitted, and it's a beast to shoot. I can't imagine what yours would be like at darn near 2 lbs lighter!
You are missing nothing with the 338/WSM. It does have more case capacity than the RCM.
My decision was based on many different things at the time. WSM ammo had become hard to get
and the bullet selection for the .323 diameter is/was not very good. The wildcat 338/WSM would solve the bullet issue so it is a good choice except the brass issue.
At the time the 338 RCM had factory ammo available and the difference in performance can be made up with proper reloading and bullet seating.
When I go into a new cartridge, I always check to see if the cases can be made from other cartridges if there becomes a shortage. (They can) and also buy at least 300 to 500 rounds of brass
just is case.
It has been a great little cartridge and is very handy in the little MOD 7. I have very good accuracy and have found nothing It would not drop in there tracks.
As I said earlier, I am not a big fan of compact/light rifles, but for this application I had to make some concessions, Surprisingly, I am enjoying it and use it often. I have a low power, light weight scope that works well for nighttime hog hunting and there are no second shots required. I would not hesitate to use it on bear or elk.
The longest shot I have made so far with it was just under 300 yards, (Just a chip shot for it) and have no doubts that it will kill at much longer distances.
