Re: Dad Puts Elk Down!!! WITH VIDEO
Cool video. That 300SMK really puts the whack on elk doesn't it.
The 338 UltraMaxx can not really be lumped in with the term improved. To be an improved you would have to be working with a case that can simply be loaded on the parent case and then fired in the improved chamber. Just as in the 270 Allen Mag the shoulder and neck junction are moved forward and this makes it a true wildcat. This one either needs a false shoulder or the bullets jam seated to hold the case against the bolt face for ignition. The best description would be more accurately as Larry has said, it is the 270AM necked up to 338. You might also describe it very loosely as an 338 Edge super improved + headspace. Once run up to max loads it should have an advantage on any of the 300RUM improved based 338"s.
I have been watching the development of this baby long before the reamer was designed. The name was derived from the fact it is "THEE" max interpretation of the 338-300RUM case configuration.
