I bought my 338 win about 35 yrs ago when I moved up to the Yukon. It is a Winlite mod 70 and at 6.2 lbs, it is a handful. That said, I hunted with it almost exclusively for the next 20 yrs and shot more game, species and total number, than all my other rifles combined. To say it is a favorite of mine would be a gross understatement.
I went all out with this cartridge! I loved everything Adam Weatherby was selling on it and purchased a custom rifle from the Weatherby shop chambered in 338 RPM. Living in Alaska I wanted that all around rifle for sheep up to brown bear, I think another aspect of this is that gets over looked is it was developed for a purpose. It’s light, it’s efficient, and the rifles it’s chambered for are more capable than we can be. But I love my 338 RPM 👌🏼
I had no idea the 338 Winmag and the 338 WBY RPM were so close performance. For for some reason I had it in my head that the winmag was a bohemith of a sledgehammer and the Weatherby was a more dainty sleek new-age mountain cartridge
You should check the Cartridge case dimentions and powder case cap. to compare(I like Nosler Load data, Nice pics). Back in the day Wby. brought out the 340 to out perform the 338 WM. But it's a handfull. The 33 Nosler about the same as the 340 Wby. Today a Shorter, fater case for Std Actions(Some Short/Med actions) the fade. More modern, but with the same performace.
"THE" Elk cartridge is the 340 Weatherby. I shoot 225gr. at over 3000fps and 250gr at 2950fps. But it's a long action, and one shouldn't want one in a 5# gun, LOL!
Every Elk I ever killed was either with a muzzle loader ( Hawken Rifle) or a 7mm REM Mag. My retinas are still attached and my shoulder socket is still intact , lol.
Those Wby's fit a Mag. lengh action 3.7-3.8". The 338 WM and the 338 RPM in a Std long action(30-06 Size). That's the action(3.8") I chose for a project in 7mm Rem Mag. A bit whimpy compared to the 340. But🤣
@@donaldmartin4980 haha right! I’ve seen a lot of elk die to 243 and 270s! Got rid of the Ultra Mags and I’m in it for short efficient cartridges now 🤣
The ammo companies are to blame for rounds like the 300 WSM and 338 WM not being available when there are tons of guns out there. We don't need any more 6.5 Creedmoor ammo or the redundant 7 PRC. I like the direction Weatherby is going with the RPM rounds to the point where I hardly think of any of the older rounds any more even though they are good cartridges.
@@chadperry4021 True, but it has been around for a long time now and is quite popular. It fits into a short action and is very efficient.We already had the great 7mm RM and the 28 Nosler beats the 7 PRC. It's a good round but we didn't need anymore 7 mm rounds.
Just playing devils advocate. I was in high school when the 300 wsm was released after the 300 rum. The wsm’s got a lot of hate for doing nothing the 300 win mag didn’t already do and copying the 300 Dakota.
Really wish Weatherby wouldn’t have put SUCH a short barrel on their Backcountry rifle chambered for this cartridge. An 18” barrel takes it below 35 Whelen ballistics, and results in enormous blast. A 22” barrel would have been a much better choice IMO.
It's like comparing a 300 Weatherby mag to a 300 win mag.They are both 30 caliber,the Weatherby goes faster,but kicks the crap out of you.The 300 win mag in a rifle that comes in at 10 to 10.5 loaded with a bi-pod is perfect.I like a straight stock,no monte-carlo hump.The hump gives more felt recoil and doesn't help in my opinion. The 338 win mag is perfect for moose elk bear but not deer.Get a nice 06 or 270 for the deer
🕵️♂️ As You Know, the 338 WM has a Larger Frontal Area (Makes a Bigger Hole, Going At Similar Velocities and Using The Same Bullet Construction) than the 300 WM and Can Shoot Heavier Bullets! Suprisingly, the 338 WM isn't that much different in recoil, though! So, Let's Run the Numbers in Horneday's Ballistics Calculator (Using My Typical Hunting Conditions - Elevation = 8,000 ft, Temperature = 32 F, Wind, = 10 mph, Relative Humidity = 20%, Zero = 200 yards) and Compare: 338 WM - MV with 225 grain Nosler Accubond (B.C. of 0.611) and 71.5 grains of IMR 4350 powder - MV = 2,882 ft/s; Drop @500 yards = -36.3"; Drift = -10.7"; Energy @500 Yards = 2,676 Ft Lbs; Recoil = 36.93 Ft Lbs! For the 300 WM using a 210 grain Nosler Accubond Bullet (B.C. of 0.661) and 76 grains of Reloader 26 powder - MV = 2,874 ft/s; Drop @500 Yards = -35.8"; Drift = -9.8"; Energy@500 yards = 2,570 ft lbs; Recoil = - 34.84 Ft lbs! So, Which Would You Rather Use on North America's Biggest Game Animals? For Me, I Think the 338 WM is Just A Better Cartridge For That Purpose! Especially, If You Were Hunting Alaska and Encountered a Big Brown Bear! 🐻
Gotta say that I love my 338 WM! Ruger M77 MKII is pretty easy to shoot in this cartridge. Also if you wanted load data for the RPM, Hodgdon has it on their website and in printed format. I just bought a Hodgdon reloading book from Midway last week that surprisingly had RPM data. Their data shows that they are ballistic twins in pretty much every way.
@ReloadingWeatherby, I was surprised to find that they had a printed book. It's not as extensive as their online resource but it still has plenty of loads. Their is also a pretty good article in it about the RPM. It sounds like, given its case size and design that it is going to be very versatile in terms of powder selection that one could use in it.
@@jeffreyherman2729except you could find factory RPM shells. That in itself is major positive. It’s weird how Weatherby quit loading for the A-Square right before they released the RPM 😅
@@MrMcfly907 I do not find it weird at all they stopped loading for it. Why would you load for a competitive better round? Confirms my gimmick cartridge statement. If $90- $130 off the shelf box of ammo is your thing, then go with it. I roll my own, it is hard to find a brass company who does not offer 06 brass. I reloaded 50 rounds 6 years ago and still have 25 or so left. I shoot it to make sure it is still on and everything I hit is one and done.
@@jeffreyherman2729 who said I don’t roll my own? When you build rifles and shoot wildcats, it’s kind of a necessity at some point. But all I’m saying is that not everyone else has the time or inclination to do their own loading. I don’t like arguing on the internet, but just pointing out that even if it isn’t a reason for you, doesn’t mean it isn’t a reason for everyone 👍
Of Course. If I ever get a 338 it will be in 338WM, Same cartridge size and performance. If you got a bit of space between bullet tip and magazine, could seat out the bullets a bit, beyond OAL
Personally this hits a spot for me. I have an American with rust on the barrel, chambered in 30-06. I have already decided to build on it and in the beginning I was thinking 280ai. Finding this cartridge I have been sold. I gravitate to bigger is better and with this bolt face I’m excited to built a trim American (because it’s what I have and I’ve wanted to build something for a while) with win mag performance. Pretty sweet if you ask me. With factory loading
Still swear by my 340 Weatherby. If I need more speed, for what I don't know, I have a .30-378 that cranks out 225 grain bullets at around 3100 fps. Who could ask for anything more? 😕
I can get a 338 WM in a Browning BAR Semi-Auto! So, it is the 338 WM for me! Though, I would rather have a 338 Federal in a Semi-Auto for Hunting Elk in Thick Timber and for Home Defense!
Actually I purchased a used 340 Weatherby used when I was looking for a caliber that would reach out further than the 300 WSM. I was hand loading the Barns MRX bullet which is no longer in production but I bought all of them I could find when I heard they were discontinued
if i were buying a 338 today, it’d be a backcountry 2.0 in 338 WBY RPM …and my preferred load probs the 185 gr (which has barely more recoil than my 444 Marlin, and stock+pad+break or suppressor probs overcomes the diff)
The average prices for both are much less expensive than expected given the current economic situation. Using a rebated rim is kind of a head scratcher. Maybe, Weatherby chose a rebate rim to avoid patent infringements.
338/378 is still my theoretical "go to" 338. If I need a .338 ,I'm shooting sending in w devastating intentions lol. I'm biased to the 378 cased as I loved my TRR 30/378. I'm still crying about selling it years ago :(. The load data out the Sierra manual for the 30/378 created an accurate laser of a rifle.
Both are great. What puzzles me is why Weatherby didnt just chamber the 338RCM because its already developed and the same thing. Ive got the 338win and the the 338RCM and i like both and both are quite good. The great thing about the weatherby is the rifle its chambered in
I don’t care what anybody says, I only have full length barrel magnums. Weatherby claims the 338 rpm has magnum performance out of a 5 pound rifle with 18” barrel. Sounds like a terrible time to be a shoulder if you ask me
i’ve had my 18” barrels 338rpm backcountry 2.0Ti for almost a year now. in all honesty, it’s not that bad with their muzzle brake. recoil is comparable to a 300wm maybe even less. also, i plan on suppressing mine so it doesn’t matter.
338s are cool I like 375s, they can be shot by the same people that can shoot 338. Although I think 338 win mag is a flagship cartridge and has served for years and others are compared to it in the same caliber. But, a 375 H&H will shoot a 300 gr bullet with the trajectory of a 30-06 shooting a 180. I don’t know how it compares to 338 though. I still like 338 rifles tho I think there good
if i wanted this performance, more than a .35 whelen or .338 06 but still a bigger diameter bullet, in a light rifle, im going with the .325 wsm. a little more efficient and bullets 20 grains lighter equal less recoil, and in a 5-6lb rifle that matters to me. i cant imagine an animal is going to notice the difference between 0-400 yards, where you still have the speed for bullets to reliably expand. i do agree, i think the weatherby rpm is very cool, and i'm also sad the .338 win mag is fading away. i imagine you will always be able to get ammo in alaska and africa for it though.
@ReloadingWeatherby nearest I can tell, it's 3gr at most. So, unless you can seat the bullet way out, I don't think there would be any noticeable difference. Pretty great combo in a 6 lug action.
I got 338-06 338 win mag 340 wby 338 lapua and the ai 338 rum 338-378 and 338 khan iv bin shooting the 338 win mag for 24 years i can get 2900 fps with a 225 and from owning alot of 338s the 338 win mag is the best all around for hunting and i dont get why people keep believing the inter net and believe that these smaller cases can match bigger in speed its just a lie to get people with not much knowlegde that google everything to buy these smaller rounds and think they are going just as fast

So, unless you can seat the bullet way out, I don't think there would be any noticeable difference.
Pretty great combo in a 6 lug action.
If Weatherby would lower the price of their ammo they would sell more rifles.
Is efficiency mostly dependent on main case diameter in relation to bullet diameter?
Probably an oversimplification but efficiency has to be bound by physics somehow, right?
For me it's how much powder are you burning to get a certain weight bullet at a desired velocity.

😂 Boy, Is Chuck Going To Be Mad (😡) When Chuke (👨) Becomes the First Person To Kill A Bigfoot (🧟♂️) With His 270 Winchester! 🤣
