I am still waiting on my upper kit to show up but I have been busy getting everything else ready. The lower is assembled and ready. I have some test loads ready to chrono. Now my mind turned to magazines. I have a heap of GI mags so I though if I could get a good follower I should be all set. Other than the single shot followers that many appear to use I could not find on 450 Bushmaster specific follower. I expanded my search to include 458 SOCOM and 50 Beowulf and came across a promising 458 SOCOM follower at http://www.calegalmags.com/458-SOCOM-Ma ... _1397.html. I ordered three of them and they arrived today.
Now if my upper will show up I can test them and let you guys know if they are worth buying.
