I'm considering changing a 111 .270 CF to a .223. I'm already building a 7 twist .223 on a 110 that was a .223 from day one, but I recall something about a LA.223 bolt head being different. If I use baffle #956092 from midway will a standard bolt head work? If not what head work work, and where to buy one. Thanks for the help, Slip.
