New 358 Win Improved

338F 225gr Accubond @ 2500 fps
+2" @ 100y, -10.5" @ 300y, -28.5" @ 400y
400y velocity = 1950 fps, energy = 1900 ft lbs

358 Win 225gr Accubond @ 2500 fps
+2" @ 100y, -11.5" @ 300y, -31" @ 400y
400y velocity = 1800 fps, energy = 1625 ft lbs

Just a fun comparision to see how close the two are:

.338F 225gr. Accubond @1950fps = TKO 21.19
.358W 225gr. Accubond @1800fps = TKO 20.71

A difference of TKO 0.48 which is the equivelent of a high powered .22 air rifle at the muzzle, a 2.5% "improvement" over the .358Win, not even worth comparing. The .338 can't however compete when you start comparing with heavier bullets as they exceed OAL.

No contest win to the .358Win.
 
Did you confirm those velocities over your chronograph?

Will post when I've finished sorting out my Frontier over the next few months. I won't get published data as it's only a 16 1/2" barrel though, so on that score I'll have to concede to TB's .338 Light :D

I've shot the 250gr Hornady round nose in the Sako 85 338f to 2325 fps. Haven't tried it yet with the Ruger, will do so later this summer if I get time. I also have some 250gr Interlock spire points which I could try too, just for kicks. They will fit fine in 338f, same ogive profile as the 200gr Interlocks...just gonna take up more powder capacity. Although not something I would hunt with, a 250gr spitzer @ 2250 fps out of a 338f should perform nicely on game at moderate distances. Expansion should be no problem out to 350 yards depending on the bullet choosen ;)

Nosler doesn't even list 250gr data for the 358 Win because it's so patheticly marginal. Contest win? LOL
 
I think that's something to watch with both the .338L and .358W. Most of the heavier weighted bullets are designed for larger capacity cartridges and performance at higher velocity. This may limit their use in the shorter chamberings to shorter distances. So as it is every fps is needed, seating deeper for the longer heavier bullets is a solution but you're only further hampering their performance, and as it is the .338L is struggling to show it's worth. :stirthepot2:

The title of this thread really needs to be changed to something more suiting, how 'bout instead of "358 improved", lets go along the lines of the mighty 375Ruger, "The New King of 375's."
how about: 338 Federal " The New Court Jester"
Has a nice ring to it, does it not?
 
we could call it the 30-06 Improved as well, after this showing tonight

185gr TTSX @ 2750 fps, with 48.5grs IMR8208xbr

I was wondering if any 358 Win owners could post a load recipe for a bullet that will drop only 24" at 400y from a 200y zero, and still have the muscle to break bones at close range on elk and moose? ;)
 
Nice shooting, impressive velocity as well. Good cartridge, it and the 358 are ballistically two peas in a pod.
