My mission to find the best short barreled big 338!!!

How much of a difference from a 338NI to a 338LMAI?
The 338LM came out in "89" and the 338NM in 2008. They are almost identical built from a 416 case and both have pros and cons.
Thanks. You shoot more 338s than anyone we know.
.338 Lapua Magnum vs .338 Norma Magnum.jpg


Jimmy Sloan made it in 2008 with the help of Dave Kiff.. then the military adopted it .. basically just like everyone else they wanted a cartridge that would feed through a mag with the bullet above the neck shoulder junction,,

Built right build the 338 lapua will over come the 338 norma in velocity...is it mind blowing? No.. not like going froma 338 norma to a 338 reaper

How does a 338 NMI compare to a 338 RUM velocity-wise (CFE-9 for the RUM) and is there a reason one would be better than the other for a short barrel?
From what I've experienced they will be very close and they will burn same or close to same amounts of h1000 while using same bullet weights
the accuracy will be great with either ..

You sir, just built my dream rifle. How's the recoil in that setup with the ultra can? What would you compare it to a non-braked caliber?

For me it was less felt recoil using the can, but not bad at all with the brake. continuous shooting it get's rough, but that's a whole day of blasting steel. It is way more manageable with the Ultra, I use it off a tripod all the time
 
The Norma was built around the 300 gr bullet and shines over the Lapua past 1500 yards.
Do you shoot the 338NM with 300gr otms and have the data to backup your statement?
We are always looking for a better cartridge and if the 3338NM is better that's great.
However I did look at the ballistics with PROS and CONS between the two.
Would like to see the real world data from you for your statement.
What "SHINES"???
We have custom JGS Reamers for 338LMAI and also shoot the 338LM.
If there is the 338NM with better results - what is the percentage of better ballistics than the 338LM and justified to make the change?
Thanks

Send me your data on the Lapua and let's compare. From the pictures posted above of the Lapua case versus Norma that same article, by ballistics I believe, went into great detail between the two. Yes I always use the 300 gr bullets, I haven't used anything. I don't own a Lapua so you will have to share your real world data so we can take a look.

have you compared the 338NMAI versus the 338LMAI? what barrel lengths and twist rates are you spinning up your barrels in? Once I get all the data we can do a nice detailed review. I will send in all my data, loads, brass, barrels, etc. It would be a fun comparison :)

Honestly ... this and my edge were very pleasant !! I mean my 14 year old shot the edge and loved it!!

obviously a brake is going to work " better" as a recoil reducer but the pluses of the can out way the negatives by a long ways!

You are the person "waveslayer" that stated "The Norma was built around the 300 gr bullet and shines over the Lapua past 1500 yards.
so you post your DATA!
Don't ask me for data to dispute - I am not doing the compression - You are the one making the statement!
I personally think all the "Good Design 338s are GREAT for LR Hunting.
It is just that there ae so may cartridges that are basicall the same. Just that different manufactures want to get into the game.
Look at all the Needmores!!!! They are basically the same cartridges as the needmores. It is just that Hornady and Creedmore got together and offered a 1:8 twist in a 6.5. They blew out the .260 Winchester with a 1:9 twist in rifles and then the Snowball just kept rolling. Now you have all the Needmores from 6mm, 25, 6.5 and a big following in PRS.
The .308 Winchester Case has got to be one of the "BEST & USED" cases for Hunting or Military in the 21st & 22 nd Centry.
Name me another "Better" Cartridge Case for Hunting, Target, and Military that is being Modified in different calibers to this Date in History!!!

NONE Military Big Mag
OK beside the 300 WM, 338 LM
