Hey y’all,

I’m new to forum and the 450BM, but I am an avid reloader and hunter. I have been reading here since I purchased/built my 450BM AR aka Thumper. So far this forum has been very helpful. Hope to keep learning from everyone.

Whenever you read any posts by Wildcatter just know that you are reading the knowledge from the actual inventor and patent holder of the 450 Bushmaster cartridge and you need to be paying attention.

Hello mudbug and the rest of those on the forum.

Hello all. Just joined up here the other day after having read the forum as a guest off and on. I have been trying to get my 18” upper to feed reliably but so far no luck. I am going to do some high frame rate recording of the ejection port at some point to see what is going on. I’m using mags that are set up for 450 with the single stack follower and I have added additional clearance on the front lip of mag to keep the case mouth from catching.

Hope to learn some more and when I get some video to share, maybe some of the experts here can point me in the right direction.

Safe shooting,

Greg

I would be interested in seeing pictures of your magazine springs. Laying next to the magazine.

Hi all and thanks for letting me in. I'm new to the 450b and I'm looking forward about learning more about this round. I purchased it primarily for hog hunting on the recommendation of the outfitter we use. I purchased the 450b in the bolt action Mossberg Patriot with the 20" barrel. I almost have it set up the way I want and I'm looking forward to taking it on our annual hog hunt in Florida come January.

I can do that. Thanks from a fellow Texan.
