This report in Fox News suggests that the alleged criminal was armed with a .50 Beowulf rifle. Interesting. First time we’ve seen a big bore in the hands of an alleged criminal.
The industry consensus is the 450 Bushmaster is a success and the only big bore AR15 round that is worth supporting. How do we know this? SHOT Show 2010.
Remington unveiled not only its 18″ 450bm upper, (nicely splitting the Bushmaster offerings) but also a brand new 450bm round: the 260gr. Accutip.
Pics are from 450bushmaster.net:
A creative artist has listed a 450 Bushmaster tie tack or hat pin. It has a very low price of only $5.50. They also offer other calibers. This auction strongly suggests that the 450 Bushmaster has become a mainstream cartridge, as we note he does not make a 50 Beowulf or 458 SOCOM pin.
A fellow 450bm shooter was looking for a subsonic load. “LouBoyd” suggested using two 300gr bullets in one case. His theory:
I’m not recommending the following but I like to experiment. If I owned a 450 Bushmaster AR-15 I might try loading it with TWO 300 grain Jacketed bullets stacked together. I’d robably choose Speer #4485 soft points with moly lube added to both shanks. Quickload Indicates that 14.3 grains of Hodgdon LilGun could toss the two bullets at about 950 FPS with 35000 psi chamber pressure at standard OAL.. (SAAMI max is 40,000psi). I’m not sure that would cycle the action but it’s more likely than shooting one bullet subsonic. Being separate both bullets should stabilize but they might deform some. I wouldn’t bet on great accuracy but I don’t know.
“LouBoyd” goes on to strenously mention:
I AM NOT RECOMMENDING THIS LOAD. IT”S JUST A COMPUTER SIMULATION.
Go here to get this good deal: 16″ upper, LMT iron sights 5.11 tactical case all original papers and Geissele 2 stage trigger.
