Which bolt head for 450 Bushmaster?

[mattri]

Have an Axis in 223, converting to 450 Bushmaster.

Which .308 style bolt head do I need?

[Robinhood]

Short action .473(308)

Please keep us informed on your project. I've been toying with the idea of rebarreling my 243 Axis with either the Bushmaster barrel or 45 Raptor.

Thanks, push feed or controll feed?

[sharpshooter]

Push feed is your only choice...

[mattri]

Right as usual. Missed that the others are for the short mags.

Will I need to change the firing pin?

[Robinhood]

The Axis are designed to use the Short action bolt heads. The only thing you need to check is firing pin protrusion. It should be between .035" and .045"--- .050" maximum.

Maybe somewhat off topic, but the 350 legend would be the same bolt face, right? Have you considered that?

[mattri]

Thought about a Legend but really like the Bushmaster, and with a head swap being so easy on a Savage that's the dirrction I went. Have one on its way now��
