What's to like about .458 SOCOM?
What's not to like about .458 SOCOM?
Standard rifle bullets, 250-350gr with .45-70 Gov performance out of a 14-16 inch barrel!
What about a 20inch barrel?
There are 3 big bore cartriges for the AR that have there strong points and you will need to
look at all of the advantages and disadvantages of all three and make your decision on that
I went through this and came to a conclusion that best suited My needs for a hog and bad guy
There is the .458 Socom, the 450 Bushmaster and the 50 Beowulf.
The Socom shoots the largest bullets, 300,500 at 200ft/sec and 1300 ft/sec and a subsonic
The Beowulf uses 325 and 400 grain bullets at 1950 ft/sec and 1800ft/sec.
The 450 Bushmaster uses a 250 grain bullet at 2200 ft sec for 2686 ft/lbs of energy( No
energy's were posted for the Beowulf or the Socom).
Brass was the main issue and trajectories was the next consideration and expansion on game
was another issue.
Brass for the Beowulf and Socom is proprietary and difficult to purchase. the 450 brass
is made by Hornady and is inexpensive Plus you can make it out of 284 Winchester brass
by simply trimming it to length.
Loaded ammo for the Bushmaster is also available and inexpensive.
Regardless which one you chose I would recommend the 20" barrel and a very good Muzzle
I made My decision for hunting purposes and am very happy with the cartridge and the bullet
performance on game.
The Big bores in an AR are awesome and totally change the AR from tame to mean.
