Roger that my mistake.
I think i use H-1000 with my 20" 375 CT (352 CE)

I know where you are coming from most people think using short barrels they need to change to a faster powder. Usually the best performing load in the longer barrel still has the correct pressure curve to give the best performance. Look at a 223SBR the military don't use different loads in short barrels.Roger that my mistake.

That is why I recommended the 338-378. It is the most case capacity u can reasonably use in a 338.I know where you are coming from most people think using short barrels they need to change to a faster powder.

And as mentioned a bigger case will give better performance if both loaded to the same pressure.
There is so much mis information in this thread saying a smaller case out performs a larger case in the short barrel. But they take a low pressure standard case and compare it to handloads in a modern case that can be pushed past loading manual data and are running double based high energy powders.
Run both to the same pressure with the same powder bigger always wins.
Or step it up to a 378WbyThat is why I recommended the 338-378. It is the most case capacity u can reasonably use in a 338.
That works too but then all the 375 options come in to play like the necked down 50 BMG.Or step it up to a 378Wby
The only issue will be feeding vlds throug a CIP mag
They won't fit a long action with CIP mag thoughThat works too but then all the 375 options come in to play like the necked down 50 BMG.
I recently finished a 20" barreled Savage .338 Win. Mag., throwing 200 gr Noslers out the tube.I approach it this way.
Assuming 5000 feet elevation or higher since we're talking elk.
Now what's the most efficient bullet to get there and do work. I'd pick a 230 berger. At 2750 fps you get to 1000 yards with 1850 retained velocity which is your minimum threshold.
What cartridge will get you there. I'd like to say 30 sherman max, 300wm or 30 nosler. I'm a huge fan of the 30 nosler but feel the right powder combo in a short mag variant would do the job. Really need to play around in QL.
Also, I've been researching this quite a bit and it seems 20 inches is the sweet spot. It's not much of a drop off from 22 inches but seems to really outpace an 18.
You sir want a Sherman Max, it's a line of cartridges that use the SAUM as a parent cartridge. I'm currently building a 338 Sherman Max with a Bartlein 22" left hand twist barrel on a long action so I can seat bullets long as possible. The cartridge excels in short barrels and Allterra arms has done extensive testing to prove it. Hoping to push 250 grain bullets near 3000 fps. I'll attach the Sherman website. There is also a Sherman wildcat cartridges Facebook group that is extremely helpful.I like guns and need another one like I need a hole in the head but I have this extra XLR element magnesium chassis and I'm thinking about building a short barreled gun.
I know this has been discussed but I'll ask anyway.
I understand that short barrels castrate big cartridges and I don't care. I don't care about muzzle flash or unburned powder or efficiency etc.
if you think an 18" 338 Lapua is completely ridiculous and should never be done theplease don't respond to this thread (I felt this way a year ago)
now to the question: I want to build a strong magnum long action gun with a short 18"...or maybe 20" barrel. WHAT IS THE BEST CARTRIDGE FOR KILLING ELK to 1000 yards.
elk are tough critters and I don't subscribe to the 7mmRM being sufficient to kill elk with at 1000 with any barrel length (and yes I know it's been done effectively thousands of times)...but I'm looking for something that hits harder than that.
my initial thought is to just do a 338 Lapua (I'm already setup to load that one)...then I started thinking well in that case the 338 Norma is probably a better choice...then my brain went to the 300 Norma with 230 or 245's....
is a 300 Norma not actually faster than a 300 WM if you cut the barrel down that much????
I know we are sacrificing some velocity with a short barrel which is why I went to heavier bullets automatically...but maybe I'm wrong there
also this is not going to be an ELR gun...it's only for 1000 and less so I don't care if we take an entry level ELR cartridge and make it not good enough for ELR.
28 Nosler-375 CT...go
I'm building a 338 Max! Bartlein 22" barrel on a Weatherby Mark V long action.338 ss at elevation gets your what you want.
I will say, without any hesitation, that if you're shooting a 250gr .338 bullet at nearly 3000fps from a 22" barrel out of a case with 78gr capacity, you're WELL beyond what the majority of shooters would consider safe operating pressures.You sir want a Sherman Max, it's a line of cartridges that use the SAUM as a parent cartridge.
