I own the 338 RUM and get with the 250gr bullet using RL25 powder 2970 fps with max load. With the 225gr bullet I get 3100 fps max load with same powder. Well I'm happy with it.
Could probably go faster using a different powder. [img]/ubbthreads/images/graemlins/wink.gif[/img]

I'd also be more than happy with those kinds of numbers [img]/ubbthreads/images/graemlins/shocked.gif[/img]. Your's is the FIRST real life data I've seen on the 338RUM. Am assuming you have the 26" bbl?
Compared to the 338 Win w/24" bbl, 2900 FPS w/the 225gr is my max and 2850 fps w/any 250gr bullet. All 250gr bullets shoot best at a velocity of 2800 FPS.
Hmm, wonder what I can do next.
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!
I have no need for the larger bullets, but in my Ruger .338WM I am shooting 200 gr NBT at 3040 fps, 200 gr WW Factory NBT at 2981 fps and WW factory 250 gr PartGold at 2768 fps out of my 24" barrel. The factory NBTs go into one hole at 100 yds, and the 250 gr PG about 3/4" ctc. All the handloads I have shot will put 5 shots into 1 1/4" at 100 yards. The first three are usually 3/4", but as the barrel heats, the bullets walk.
A little more "real world" numbers for a 338rum. HS Precision, 26" bbl. Barnes TSX 210gr 92gr RL22 = 3250fps.
1/4" to 1/2" groups, depending on how good a day I'm having at the trigger [img]/ubbthreads/images/graemlins/wink.gif[/img]
G.G and I are getting 3210 fps with RL 22 and 225 Accubonds out of A stock Remy with a Tubbs (final finish) break in. 1/2 MOA with .550 BC crushes the gong at 1145 yards. I believe a 26" barrel is enough but maybe not optimal.
Well, I'm a liar. I got too good a deal to pass up the 338 RUM LH BDL. $480 and the seller said that it may have been fired but he can't tell. New condition. I am NOT going to sell my Model 70 338 WM, though. It might get rebarreled to a different caliber, however. 270 Weatherby is intriguing. First things first. Got to get a muzzle brake for the big boomer.
The critters have to win every time, I only have to win once.
More real info. I just had a broughton barrel installed on my 338 rum earlier this year. With 98 gr of rl 25, 3300 fps and ,5 moa with the 225 accubond. Barrel is a hare longer than 27 inches plus the brake.
