Hi, I'm looking at going to a 338, but cannot decide whether to go with a 338
Win Mag or a 338RUM.

I hand load and presently shoot a 300RUM in a Rem 700 Sendaro(c/w Leupold 3.5x14-50LPS), which I've loaded with 150-220 gr bullets with great results. It is a great gun and very accurate and I don't mind the recoil. The problem is that the Sendaro and scope are a very heavy combo. So, I like to go with a lighter rifle for packing around all day. I will be going with a Rem 700 XCR II (if I can find one:wink:

 I will be using this for elk hunting (killed lots of them with my 300) but because of hunting pressure and oil and gas exploration we're starting to have to hunt more and more in big bear (grizz) country and would like something with a little heavier and bigger bullet.

Has any one shot both of these and what are your opinions on recoil, accuracy, etc.,. As mentioned I don't mind the recoil and have a Sled for sighting it in.

Your thoughts and comments would be greatly appreciated, thanks in advance.

i havent done the 338 rum but i do shoot a 338 win mag. even out to omost 500 yds a 210 grain nosler will still land under the hide on the opposite side of an elk. all a 338 rum will gain you is a little more fps and slightly flatter shooting.. the cost of brass and the amount of powder you will use, can be spendy. and if for some reason some thing happens to your handloads, you wont beable to find 338 rum loaded very easily

I shoot a 300 RUM, a 338 win Mag (got two of them) and a 340 Weatherby Polar.

The markV polar is about the same as the 338 ultra.

The only advantage of the 338 RUM is NO belt. Yep I have 15 rifles with belted cases, and I really never liked the belt on a bolt action rifle.

I'm not sure what yoou woould want the rifle for, but the 338 RUM really has little to be desired over the 338 win mag. If I wanted to shoot some 300 grainers then the 338 Rum would be a good way to go. But if you need more than the 250 grainer out of the 338...maybe a 416 rem mag would work better.

A friend had a 338 RUM and had a bad experience on a moose (might have been poor placement, I don't know...nor does he). He shot my 416 with 350 grainers and traded the 338 RUM off, got the 416 and gat a super moose.

A few guys at the range like the 338 RUM and the Lapua for long range shooting. My longest range is 600 yards, so the 300 RUM works fine for me.

In shooting the RUM cartridges, I've found they are not as easy to reload for as the win mag counterparts. And they just don't seem as accurate.

in the final analyse, it is really just a matter of what "you" like. go for it.

And the Walmarts in the Rockies have .338WM on the shelves.

A .338 WM can be built light enough to carry, and still not put the scope ring through your skull shooting from an odd position.

my friend has a 300 rum and it is very picky on the powder for his reloads. i believe he had to go to retumbo to get a decent group. i would have to ask him what he uses to make shure on the powder.

I have a 338RUM in the xcr stainless with the plastic overmoulded stock. I got it for a song from a friend with 38 rounds through it. I did not really need it but he needed cash in a bad way so we both came out of the deal happy. It burns a lot of powder and gets your attention on the bench in a hurry. It is my limit for recoil with no muzzle break. Like bear said with 300 grain bullets it makes more sense and it really should have a 28-30 barrel to take advantage of all that powder. Don't get me wrong I really like it it is a load of fun but I could get along just fine with a 338 win and as was said much less problematic to buy ammo off the shelf. If you figure about 25-30 grains more powder per shot and 40-50% more for the brass the 338 win should be a better choice for you. I would not want to be the grizz,elk or moose on the reciving end of a 225-250 partition out of a 338 win I can tell you that.

Well gent's thanks for all of your feed back.

I went with the 338 win mag in an 700 XCR, got a great deal on it and I couldn't find a 338 rum anywhere (probably karma looking out for me).

Next Question, What are your favorite loads for the 338WM?

The good news: just about every bullet in that caliber was designed for the .333WM, and they all work well.

The .225/250gr Interlok's from Hornady are easy to find and are usually available, and they typically shoot real well over the 4350's.  But ther are tons of options, depending on what's in your wallet.

I imagine you have all the load data you need by now and
bought your 700XCR the year after I bought mine. I lived
in Oregon at the time and the coastal weather can include
salt air when hunting the Roosevelts. Have impressive 180
and 200 grain loads but since I am now in Louisiana (whitetails, no elk) my favorite load is a Fed 215 GM primer igniting 80.5 Grains H-414 (I worked up carefully) pushing a 160 Barnes TTSX chronographed at 3400+ FPS and
grouping just under 2/3 inch. Since the case is the same
size as the 7MM Rem Mag pushing the 160 grainers at 3100
FPS it makes the 7 very jealous because the 338 is flatter
to at least 400 yards. Guess which hits harder!! Some
say the 338 is excessive for whitetail, but if a 165
grain 30-06 or 300 Mag bullet is OK, what's wrong with
a 160 grainer in 338, the same size case as the 7MM Rem
Mag? The thing is, even on a marginal shot, they go down
where they stand and the hunt is OVER!! No hunting for a
blood trail. And the rifle is lighter than a 7 or 30 cal
mag because of less barrel weight and yet recoil is mild
and not as sharp as the others. What's not to love?

Incidentally, I had owned a 700 LSS in 338 Ultra Mag and
the first load I developed was aroud a half inch and with
the chronograph shot 3 within 7 FPS and EXACTLY as shown
in Nosler's Fifth Reloading manual using 180 Noslers.
I LOVED that beautiful laminated stock and stainless but
the 95 grains of IMR4831 wore me out, although I used a
25# shot bag and recoil was not a problem. However, the
last time I shot about 20 rounds in one session with a
low tin roof at the range, in spite of good hearing
protection, it gave me a headache that lasted into the
second day and I decided my old brain didn't need that
so I sold it before buying my last 338. I think you chose
wisely and I learned by experience the 338 Win is enough!
Hope to add a 700 Classic in 338 Win for the wood and
shorter barrel and hunting in good weather. Would not take
it out in the rain but opt for the XCR in bad weather.
The shorter barrel would probably slow me down to 3330+
FPS. Horrors!! (Not sure deer would notice the slower
bullet.) Merry Christmas. I would enjoy hearing about
your results with the 338.
