I have an old Savage 340 E in 22 Hornet. Was wondering if it would be possible to rechamber it to a 223 Remington? Hornet ammo is a bit spendy and hard to come by in my parts. I'm not interested in mail ordering ammo and I already reload for a 223. I was wondering if the 22 Hornet action and bolt was the same size as the 223 or if it was a bit smaller. T realize that I will need to replace the bolt head as well. Any ideas?
