I inquired about the possibility of a 450 Bushmaster load in the future and here is the reply I received.
Kris,
You should see a small listing in the .450 BM in our 2012 line-up. The bullet weights should be in the 200-450gr range. Please keep in contact for further info in the .450.
Thanks for your interest,
Pete Pi Jr.
