Are the .338s becoming pointless?

I'm always dogging the 6.5CM when in reality it's actually a great little round. Don't personally own one but a buddy does. My .260 is my 6.5CM. I guess I mostly just get tired of Hornady publishing load data that's so under powered for the .260. Then thumb to the 6.5CM page and the load data shows performance better than the .260. Hornady loves tooting there own horn so much that they make it easy for me to dog out that cartridge. It's all in fun really. I'd probably own one if I didn't already have a superior 6.5 cartridge to the CM.
Could not agree more but I have a 280rem 2 308’s 2 30-06’s 1 243 and a 338 ultra mag and 6mm creedmoor but if someone sells one cheap I might have one more rifle to clean

338 Win Mag is the least powerful .338 I've used and seen used on moose. So I can't speak to anything lesser. I killed one young bull at 761yds with it. Anyhow, it's a very worthy moose and big bear cartridge, in my opinion. Quite popular in Alaska in an off-the-shelf factory rifle.

I've seen moose killed with lesser calibers. It can be done quite handily with good bullets and good shot placement. But the 338s almost always impact with greater authority than 7mms and .308s. At least that's been my consistent observation. There have been times where it's made the difference between celebration and disappointment. Our moose get pretty darn big - of the Alaska-Yukon variety.
When using a 20" 338WM, does powder selection really make any difference? I figure a 100fps would make no difference.

I had a Savage Weather Warrior Stainless in .338 WM. Barrel was I think 22" with muzzle brake so approximately 20" of rifled barrel. My buddy had a Winchester .338 WM with a 26" barrel. Our rifles only had a 97fps difference in velocity thru my chronograph. Seemed odd to me that it was so little a difference but after reading other posts on the .338 WM, it's common that velocity is very little gain/loss per inch of barrel.

I don’t like shooting one and haven’t shot past 1000 yds ever, can’t say that won’t change one day, but not today. I have a 300 wm that seems to do just fine on elk and a .260 rem that does elk and all below it with aplomb. I don’t understand the need for a .338 for elk, but many don’t understand my need for A 300 wm for elk. It’s what makes forums like this fun, you learn, you try something new and next thing you know, you’re a deplorable gun owner. Happy Saturday to all
I realize the irony of my post as this is the long range hunting forum. I can’t justify it myself right now with how much I can practice and spend time getting good enough to do it ethically.

Don't know of many 7s or 30s that can even come close to a 285 Flatline (BC .968) going 3000+ out of a 338 Lapua improved or a 33XC.
If I'm not mistaken, I think those 285s need a 9 twist. Seems slow for such a long bullet. There over 2" long, that I do remember.

Saw a pretty cool feat last night, my 74 yr old man hit a moose and broke it's neck with a Ruger canoe paddle in 7mm Rem Mag (ugliest rifle I've ever seen, lmao) 250 yards and the bull was guillotined as the swamp yanked him down with nary a step made , pretty awesome sight as I watched through my scope in 15x ready to RUM it if it ran ....

with a 160 gr Partition bullet no less, broke the bulls neck and lights out

That's an awesome hunt. Congrats to him. I have a buddy that LOVES those Ruger Skeletore stocks. They are FUGLY for sure but obviously they get it done. BTW...I think those Nosler 160 Partitions are Bad *** bullets. I'd have wanted a little heavier for a Moose but they are built for the job.

I suppose you'd probably know which is better on big, big animals. I know the Core lokts are excellent in deer size game. Anything bigger, wouldn't know.
