Hey all,
So I've been browsing your corner of the inter-webs for about a week now, and I have to comment on how great this community seems to be. Great information, respectful... how forums should/used to be. Big props! The fine fella's at calguns.net pointed me in this direction for 450 Bushmaster questions.
Anywho, I've been after a big bore AR variant upper for about two months now. For the first month, I was drawn to the .50 beowulf (probably just from their PR compared to bushy's). After sorting through all the murkyness of what would be best for me, I decided the 450 BM was the way to go. Mostly, a big emphasis was placed on market support for the 450 BM round online.
So I come here with a couple general questions...
I've had my eye on this particular 450 BM upper... http://www.thegunsource.com/item/190078__Bushmaster_Rifles_Shotguns_Upper_Receiver_Barrel_Ass.aspx?SR=1
I notice the gas block is different from the majority of the ones with picatinny rails. Is there anything to say about this particular model compared to the picatinny gas blocked models?
Also, I see that ammo generally ranges from $25-30/box. Of course this is steep, but have online retailers ever been known to throw any of the 450 rounds on a sale? That's usually when I scoop up some bulk ammo.
In terms of ballistics, I've heard that the 450 BM is great at 100-200 yard kills, then limits out in force. Where i typically hunt deer annually, there's a prime spot I have taken a couple of deer from a tree stand that usually average to about a 275 yard kill, give or take. How does the 450 BM do when taking it out of the comfort zone beyond 200yards?
Thanks!
