Twas having a hard time looking at the rem site today; very slow and hung up more than a few times. I see they are playing the discontinue everything and throw out cheap crap for us to buy game again.
Hey Lefty, because it is more like 350 fps. For example if I take the listed max velocities for the 338 win mag and 338 RUM from my Nosler #5 manual and average them for each on the 225 gr bullet

338 win mag average 2787 fps
338 RUM average 3144 fps

that is a 357 fps advantage to the RUM and significant. I too grew tired of the low velocity of the 338 win mag and am now well pleased with the RUM. Now I am not a hyper velocity guy but do want to shoot a bullet with decent BC at, or very close to 3000 fps for some reason

ok...
for my #1 in 338 win I can drive my 225 hornady OR nos bullets to 2900 fps( these are verified by my oehler 35 p and the drop works out) with either h4831 or rl19 and I'm not even working the rifle. And most book data for 338 rum is 3100 fps for a 225. 200 fps it is. I can get a 250 to 2750 fps with rl19 also, and you'll have trouble getting over 2900 fps with the 338 rum; so 150 fps for that one. The #1 has a 26" bbl., but I'm talking to guys with 24" 338wins that are getting within 50 fps of me.
The 338 win is a good cartridge many here are giving short thrift. Is is very efficient and does the job well. I wouldn't mind a bit more case capacity, but it has enough to function.

As far as the OP wondering about a 338 rum; There are precious few available at present. I've only seen a couple for sale on the net today and haven't seen any locally in months. You are likely going to have to build a rifle.

Re: 338 WinMag to 338 RUM?

Lefty, for every example of someone who loads the 338 win mag to it's maximum velocity there are those with a 338 RUM who can and do load it to it's maximum which exceed the numbers you are giving here. IOW I have seen posts where someone has loaded the 338 RUM to 3250 fps with the 225 and 3100 fps with the 250. Not advocating it, just sayin

You have to have some basis for comparison and averaging the maximum velocities is a better method than taking anecdotal evidence of someone's velocity on their specific rifle.

I agree with you, one cannot compare Field data to manual data- Apples & Oranges there. I can say that my 338RUM will (& does) push the 300SMK to a 5-shot average velocity of 2780 w/retumbo. I've seen a 5-shot average of 2812 with 7828.

I'm not taking anything from the Winmag it's a fine round & coupled with the 225 CEB would probably be a dern fine critter hammer to 1kyds very easily. But a RUM it is not, never will be. There is no replacement for displacement & the RUM wins hands down.

OP, if you want to go with the RUM, I say: why not? Do what you will, afterall it's yours

Re: 338 WinMag to 338 RUM?

I never said the win wasn't slower, but you are giving it very short thrift. My brother in law has a 338 rum and my brother and I both have 300 rum's. I HAVE seen them in action.
This is becoming a whose is bigger and I frankly am tired of wasting time with it.

Re: 338 WinMag to 338 RUM?

Lefty, your not wasting your time bro. I have been reading and taking in all accounts and advice. The reason I hate, and my whole family hates the .338 Win is because for several years we hunted elk with guys that had them and they wounded and lost more elk than anyone we know. It was more the shooter yes, without a doubt. We came to the conclusion that due to the slower speeds and farther distances they were trying to shoot (keep in mind, this was 20 years ago and they were NOT LRH'ers), they kept hitting them low. One guy switched to a .300 WBY and never lost another critter. So it is like that hypothetical truck you had that was a total POS and you would never buy another one even though the newer trucks they make are leaps and bounds better and would probably never give ya a problem. I vowed I would never own a .300 Windbag or a .338 Windbag back then and never will, unless it is a donor of course ;) . Stupid I know but hey we all have our quarks.

Woods,

Would you mind throwing a .340 Roy into your calculations there? Would be interested to see how it stacks up. I am really thinking on buying a .300 Roy in the Vanguard then retubeing it with a 28" stainless fluted in .340 Roy or .338 Tejas the next year when I have more funds again. My bro has a 300 WBY right now and has everything to load for it so the only thing I would be out is brass.
