Hi guys, I have a lot of questions, my M12 is about to be built into a custom rifle, it's a 223rem I'm planning to change it to a 6.5Creedmore, this is a left-handed action, I know I need to replace the bolt head and the barrel, I bout this rifle new in 2012. and I have not shot it in about 10yrs and want to do something with it, I know the 6.5CR and the 308win share the same bolt face Dia, I see PTG has a standard stripped bolt head for a 308, but it says it's for 10/110, will this bolt head work for my application?
