450 Bushmaster Mag Mods

I think the picture says it all.
If you don't use the spacer, the 'bullets' will move forward and nose dive........sometimes.
But, you also have to move the spring forward, or they still want to nose dive.
Not simple, just wish they would make a Bushmaster Axis.
This is what works for me.

I don't have a bushmaster but I am betting this will help someone in the future.

How does it shoot?

Good to know. I'm seriously thinking of rebarreling my 243 Axis to Bushmaster. Did you make a plastic spacer?

Mine was a 243 HB. I used some old scrap plastic.

Got my barrel yesterday from Rhineland in Spring Tx. $172 shipped. Temporarily spun the barrel on the action in order to open up the factory stock channel. Really had to open it up with a 3/4" sanding drum in a drill bit extension. Barrel is tight in the channel but I've opened it up as much as I can. I'd love to find a factory Axis stock with the varmint barrel channel, the would be a perfect fit. A Boyd's laminate would be another possibility but a lot more expensive.

I looked at my 243 mag but am not sure how to safely remove the plastic base.

It has little plastic fingers that snap into the metal mag. They break easily, be careful. That is why I won't pull it apart for pictures.

My 243 mag definitely need your modifications, rounds nose dive every time. So far put 10 rounds thru my build to get it sighted at 100 yards. Now for load development.

You can but the replacement bottoms from ebay others may carry them. I need a long action.
