"best" version of the .338?

I don't know what numbers you guys are using but my own experience has shown me that the 250's will shoot flatter and get me more range in the standard Lapua vs. the 300's. Both 250's and 300's cross the sound barrier at roughly the same distance but at that point the 300's require a lot more elevation than the faster/lighter 250's. The only way to shoot the 300's effectively is by pushing them faster than 2700fps....which means improving the chamber. That being said, I was going to Improve my 338 but the modest 10% gain still leaves me at a disadvantage when playing with the big dogs. The standard 338 Lapua will get you to 1 mile easily. After that you might as well pony up and start shooting something based off the Cheytac case or a 50BMG. Anyway, just my opinion...[/Q
I'm using Litz own data. I just plugged in the 300 grainers and they go subsonic At 1700m with a 2700fps muzzle velocity. The numbers don't lie my friend. For a 1500m tgt with a 200m zero the 300's need 16.76mils at 2700fps. The 250's with 3000 fps and the same distance need 17.12mils. I'd say this is the magic range where the heavier and more slippery bullets really start to shine.
 
Agreed. I just punched in our 250gr scenars from work at 3000 fps and they are subsonic at 1413m. The 300's must be at least 300m further than that even. This was using my applied ballistics kestrel with Litz data.

Sorry if my broad generalization was only within 92%.
I was also considering the .338 until I found .50 BMG ammo cheaper than the Lapua Magnum.
I don't mean to take the .338 down a notch, it's an excellent cartridge. Unfortunately you end up paying more for the name than the performance.
 
Swissinn, I have the utmost respect for the work that Mr. Litz does but unfortunately my experience differs from his numbers. I'm talking about comparing 250gr Scenars to 300gr Scenars in my rifle, a PGW Timberwolf. Your experience or someone else's may differ.

Agreed 100%.

Here you go.

Better crunch your numbers again. Should be around 1800m or so at sea level.

When will they make a .338-30mm Vulcan wildcat?
That would keep everyone's bullets supersonic beyond a mile, and the .338 would remain the undisputed greatest bullet of ALL TIME!!!
Is there an emoticon for sarcasm?

Sand in your vag? If you've been a good girl maybe some Massengill will turn up in your christmas stocking ;)
 
I don't need anything more than my regular old 338 Lapua. It is capable of shooting further than I am and it is easy to find reloading supplies for. Anything more is just a pissing contest to me. I have a hard time even finding anywhere I can shoot beyond 1000yds.

Love my DTA SRS

Yes there is, would you care to lick it out?

Want a cartridge with only 15% more kinetic energy than a 300 WM at triple the cost?
If so, Lapua has the answer...

.338 Lapua Magnum!!!

Wow looks like someone got a little sensitive over this subject, maybe try getting your facts straight before you start calling people princesses. The OP asked which .338, there was no mention of a .30 cal in his post.

Where does a 30 cal cartridge even enter this discussion? Stick to your 300WM if that's what you like using, none of us are bashing it... well, I mean I may start now, but...

No bashing the 30 cal! I love my .300 Lapua Magnum! Some on here might have a heart attack... It uses expensive 338 Lapua brass and expensive 230 Berger hybrids. I can assure you of one thing though! No 300 win mag will ever come close to its performance.

I don't see how mentioning an APPROXIMATE supersonic range could be confused with a fact. Funny how some people get all wound up soooo easily over something so trivial. How dare I low ball the supersonic range of the .338 by 100 meters! Time to take a deep breath, readjust your tiara and get back to shooting, PRINCESS!
MWAAAAAAHAAHAHAHA!

There are many that wince at $1.00 per shot, others of us have no issue waving bye bye to $5.00 or more, although I do go a little easy shooting my 20MM as every time I touch the trigger $75.00 goes down range.

I shoot both a 338 Lapua Improved and something I dubbed 300 Awesome, which is 338 Lapua Improved necked to 308 cal. Iget the 236 gr Chinchaga bullets doing 3400 FPS, there by needing 15.5 MOA to hit the 1000 yard gongs. To date I have not built another so have no additional feedback to share.

Swissinn I would love to talk further and compare notes on what your experiences are with the 338 Lapua necked to 30. Maybe another thread is in order so as to not hijack this 1?

OP
We build between 75 and 100 338 Lapua Improved chambered rifles per year. My own experience is that 300 gr SMKs leave the barrel at just over 3000 FPS, typically 3025 to 3050 seems to be the norm. They all seem to need about 19 MOA for the 1000 yard trip. We have several clients who push this caliber well beyond the 2000 yard mark. We also have a couple who push 208 gr Amaxs out of 300 win mags to 2200 yards, so yes it can be done.
The difference between a hot-rodded 30 cal and a 338 is very evident by how much the steel swings at the 1000 yard plus ranges.

The differences between the assorted chamberings is case capacity and velocity. 1 unique thing about the 338 Lapua Improved is casing life is seemingly endless. To date I have over 43 reloading from the same casings, this seems common for those of us shooting this particular chambering.
 
THe 330 Dakota is another 338 caliber worth noting, brass is available along with loading data,
the cartridge is based on a shortened 404 Jeffries case but I have also made the cases from RUM cases, they work very well.
Power wise it is nipping at the Lapua heels but it works through a standard 30-06 length action since the cases
are only 2.5" long just like the 30-06 cases, the cartridge come to within 50 to 100 fps of the Lapua and in cases where
one has a fast barrel will in fact beat the Lapuas. Very underestimated cartridge.

Rick....I know this is a question that's highly variable, but what kind of barrel life are you seeing with the .338 Lapua Imp?

Better way to put it....how much less than a standard .338 Lapua?

Not ever owning a SAAMI spec style 338 Lapua, I honestly don't know how it compares. My last barrel ( I am on my 5th rifle now as guys keep throwing $$ at me for my personal guns and I seem to have little no power) I got 2785 rounds before it totally crapped out, at about 2100 to 2150 is where I started to notice accuracy starting to fall off. I AM rebarrelling this action and NOT selling this rifle!

Like any barrel how hot you run it will determine longevity to a large degree.

That seems pretty good for a hot-rod...more that what I would have expected actually.
Hmmm...my interest is peaking on this one!
