338 Ultra isn't as overbored as the 300 in a standard 26" barrel. ie. more efficient.
I was considering going to a 300 RUM from a 300 WM but looking at reloading tables and actual chronied results using industry standard 24-26" barrels, the ultra is not significantly faster. Where I understand it shines is in custom long range rigs with 28"+ barrels to burn up those hefty loads of slow burning powder.

alec ouellet,
I own the 300 Win, 300 Ultra and the 338 Ultra.
Of the three if I had to pick just one it would be the 300 Win.
Of the 300 and 338 Ultras I would choose the 338. Properly loaded (to industry standards) the 338 Ultra will drive a 225 Nosler to just under 3200fps. If it can't be done with a 225 Nosler at 3200 it just can't be done. The slight advantage in trajectory the 300UM offers over the 338UM is of no advantage to the hunter. No matter what caliber you are shooting once the target range gets past 350 yards or so some form of trajectory compensation must come in to play so the term "flat shooting" means very little to me. The 300's greatest advantage is in the wind...The 338 on the other hand is a serious step up in the killing department.
The problem with these monsters (and the reason I recommend the 300Win) is the recoil they generate. Serious enough recoil to make accurate field shooting a serious issue for all but the most seasoned riflemen.
Put two shooters together one with a 30-378 and the other with a 30-06. Ask them to shoot a target 600 yards away and the best shooter will win every time.
Inside 350 yards the fast Ultras are of almost Zero advantage over most other cartridges.....So ask yourself honestly how often you shoot farther than that?
I actually found recoil much harsher with a friends factory remington 700 than with my own rifles.My own rifles were built with heavier contour barrels,mcmillan stocks,and had decelerator pads installed.Most people that fired my guns were very surprised at how mild the recoil actually was.Even a friend that owns a sendero in 300 ultramag commented that he much preferred to shoot my rifles.
I hate the fact that it’s only good for 1500 rounds. Makes me not want to take it to the range much but I really need more practice with it so I can be confident shooting it in a real world hunting situation. I bet I won’t fire more than 60 rounds a year though it.

The 300 Ultra is at it's very best in wide (WIDE) open country in the hands of a seasoned hard core long range shooting junky.
That the 300 ultra produces awesome energy figures that really gets the attention of deer sized game does not make it a better bear (or large game) rifle than the 30-06, quite to the contrary if I had to stand behind a 30 cal in a bear fight I would much rather stand behind a 30-06.
Well to make a long story short the front of the partitions blew off in the hide and then the back half made slightly over bullet diameter holes in the lungs.
