Is it possible to change the bolt face on a Browning A-bolt like you can on a savage? I guess I am not sure about the savage either but I was thinking that if you knocked out a roll pin you could just exchange it out.

The bolt face on the A Bolt can be removed and replaced. Looking on the Browning site the heads are $45.50. They show one bolt sleeve and body for the std and short length so I would assume you could switch from 06 head to magnum. The various short magnums and 223 are listed separate.

Check out their parts list.

Midway sell em. They drop ship from Browning and charge an extra shipping charge

Thanks guys, I have a .223 wssm that starts out shooting about 2" groups but the size doubles with each three shot grouping. I like the feel of the stock and I like the action, so if I can rebarrel this to a trip duece with a medium heavy barrel it would be perfect.
