338\" 300g SMK

Was thinking about running some numbers for 338 RUM and the 300g SMK. What are you guys getting velocity wise out of the standard 26" barrels. Is 2800fps reasonable? Just curious. Thanks.

25-06,

Fairly sure you won't get 2800 out of a 26" tube. I get 2900 out of a 300 case necked to 338 and a 30" tube. I would guess that 2700 is a lot more likely. Good luck.

Re: 338\" 300g SMK

I would agree with Shawn on this one. 2800 fps will be pretty hard to reach in a 26" pipe with the 338 RUM. Guess it would depend on if you wanted to reload your brass after the first shot [img]/ubbthreads/images/graemlins/grin.gif[/img]!!

Wildcat Bullets offers bullets in the 275 to 280 gr range in ULD RBBTs. You may want to look into these. THey are a good medium heavy weight bullets that offer great BC and velocity potential in the 2800-2850 fps range in the standard 338 RUM. This by the way is plenty of velocity for extreme range shooting with this class of bullet.

Nothing wrong with a 300 gr ULD or SMK at 2700 fps either for that matter.

Rem 25-06

I ran the numbers for you on the quick load program
300MK 338RUM
with various powders 2650fps is the best i found.
================================================== ==

I have a 338-378wby imp. that shoots these 2750fps .250moa at 300yds with a 26"bbl. (Light carry rifle)
Great bullets, give them a try. dont worry about the speed. [img]/ubbthreads/images/graemlins/wink.gif[/img]

Re: 338\" 300g SMK

Thanks for the quick responses guys. I dont have the rifle, just was curious as to what one could expect. I was maybe thinking of rebarreling to the 338 but I dont know, I think right now, its a far off thought. I just wanted to run the numbers in a ballistics program to compare to the 30 cal bullets. Once again thanks.

I am getting about 2625 with 300 smk in my 338 rum with 26" tube. fun gun to shoot! those big 300's really let you know when you hit something. You might want a brake on the gun [img]/ubbthreads/images/graemlins/blush.gif[/img] they have a little recoil in a 10 lb gun!!!!!!!!!!!
