I looked for a section on Moose hunting but did not see one. I am of the understanding that Elk are tougher to kill than moose so with that I thought I would ask here.
On another site I visit a guy stated he uses Sierra Match Kings for hunting. He states it's similar to using the Berger VLD. They enter and then dump all energy inside. What would you use out of a 300WSM with a 24" 10 twist barrel-Mcgowan. I am thinking 175gr BTHP Matchking. All I have ever used are remington core locked out of my 270. Also I have heard the A max is a good choice. I am starting to do load development now.
The Match King IS NOT for big game hunting, as it's designed for target shooting and that's why they gave it that name. Use a good bonded bullet for elk or moose that will penetrate deeply, as well as exhibiting maximum expansion like it's designed to do.
I have a 325 WSM and have taken a handful of elk with it with the 200 NAB.This is a light packer abolt and not my main gun, just real handy. I have always shot larger offerings. I shot a 52'' MT bull moose with my 340 WBY, 225 gr partition and bull just stood there, I center shoulder shot him offhand at 100 yrds on purpose because I didnt want him going in the pond. He turned and walked off about 25 yrds then just bedded down and cashed it in, the moose can really soak up a high energy shot.Dont be afraid to shoot twice, they have a huge chest and a high lung can bleed out inside and not offer much tracking and it is always thick where they live, here.
the only matchking offerings that are suitable for big game are the 300grain (.338) and the 350 grain (.375). These two seem to open up well, but more than likely its because they're already pretty big before expansion.
If it were me I would go for the Accubond or the Barnes TTSX.
