Funny story...I am at a match standing next to a few well known shooters and a few guys I did not really know. The subject of AR15.com comes up and a thread on there. I said I do not go to that forum but I ask more about the jist of the thread. One of the unknown folks pipes up and tells me I should go register and contribute over on AR15.com. I told him that any site that bans me for upsetting a sponsor of their forum for stating facts is not a place I care to be. He sheepishly replies that he can get me unbanned as he is one of the founders of the site. I declined, but thanked him anyway.
I think the law changes in some states as well as the continued support will keep the .450BM growing slowly. The AR15 market is REALLY soft right now and folks are searching for new an innovative...which comes back as renamed and repackaged. For me, the .450BM is the only cartridge that I was willing to try stepping away from anything but a barrel change.
This is kind of interesting and I would like to try a .450 in it: http://www.thefirearmblog.com/blog/2015 ... artridges/
