I know not the best platform for such a cartridge but it is a start and once it becomes time for a barrel I have an action and a fair bit of range time/ load work up under my belt. I am not to worried about the stock thats an easy fix.
I did a couple of searches and found a few posts about bullets for the ultra. I have been trying to get some AB's in 225 or 250 but that is a pretty popular bullet in both weights for the 338 Win mag and a lot of guys shoot them round here so for now SOL. I did manage to land one box of 300 MK's which from what I read are not probably my best choice. When I can drive the 225 AB quite bit faster so it will take a fair distance for the 300 to come into its own, plus the recoil with the 225's in the factory stuff in this rifle with no break is my limit but is managable.
I can get lots of load data and have been reloading since I was in my teens so no issues there with making decient ammo. I have all the usual suspects for powders for this cartridge Rl 25 Imr-7828 H-1000, Retumbo H50 BMG and so on.
I know there a quite a few shooters here that have loaded for the ultra. So are there any qirks with this cartridge that you know about or have experienced? Any info from experence would be great.
Midway has loaded ammo with the 225 and 250 from Federal and nosler.
Also they have the 250 grain accubond in stock but not the 225grain.
As you said the loading the 338 RUM is strait forward and the powder choice is plentiful.
I use H 4831 sc in mine and can safely shoot to 1100 yards on elk.
