Started out as a 223, changed the bolt head and obviously the barrel to turn it into a 450 Bushmaster.
Went with a 1:16 twist so I can shoot heavy for caliber cast boolits.
Ideally would like to use Keith style boolits in the 300+gr weights and keep them subsonic.
Will be posting tons of questions in the other forums :)
