.450 Bushmaster uses pistol diameter bullets. It was still very new then and wasn't sure how bullets designed for pistol velocities would perform coming out of a rifle. As far as I knew and still know Hornady is the only maker of ammo. That may have changed now, have not looked in a long time.
.50 Beowulf ammo is much cheaper than the .458 SOCOM. That was a big deal to me since I do not hand load at the moment. It had some choices a few different commercial loads available, though there were very few commercial manufacturers offering it. I am not 100% certain but does it not use pistol bullets as well? It was based on the .50 AE case was it not? I think there are some Barnes bullets available for it and I would trust those.
.458 SOCOM factory ammo was running about $60 a box when I was looking. It uses rifle diameter bullets which is a huge plus over the .450 Bushmaster IMO. It also gives the handloader more option to work with in terms of bullet choice. It's a bottle neck case which should, in theory, give it better feeding reliability. It also has some good support from Rock River and Wilson.
Like I said I am no expert but those were the things I considered. Something's may have changed since I was researching them. The SOCOM is probably the best choice on paper, but the wolf and bushmaster would be cheaper to feed factory ammo to. I think they all perform similarly, but the SOCOM would be the clear choice if going subsonic were in the equation.
My reasoning lead me to the 6.8, far more punch than the 5.56, lots of factory loads available at reasonable costs from multiple sources, and much flatter trajectory. It had lighter recoil for faster follow up shots, more magazine capacity, and what it lacks in power compared to the thumpers can be made up with by shot placement. That being said I still like the idea of a thumper for woods hunting but think I am going to hold out for a commercial .35 caliber offering. That should flatten the trajectory a little more but still hit plenty hard.
