Grenadier,

Thank you for your advice. From what I have been checking, unfortunately, no 450 Bushmaster uppers are available anywhere - not from Midway and Bushmaster themselves are out of them. 458 SOCOM uppers are still available from Rock River Arms, though, and ammo is available for both. I have a beautiful 45-70 Siamese rifle that Huvius gifted me and which is unblooded. It is going to have to be a SOCOM unfortunately, though, I have found a good source of low priced lowers and I shall build a Bushmaster as well when they become more available.

When you're arguing over who looked more beautiful, Marilyn Monroe or Grace Kelly, I guess the best thing that could happen would be for you to have both on your arms, and at the same time.

Good hunting!
