im trying to convert my savage 11 from 223 to 243 while i understand the basics im looking for some specific information so here i am

i understand my 223 rifle has a bolt face .384 in diameter and i need a .470 bolt face and of course the new barrel go and no go gauges and so on my questions are primarily about the bolt face

does the .470 bolt face have to be a short action bolt face i have a savage 110 in 30-06 after a bit of inspection it appears my stock firing pin will be to short for that bolt head but some clarification would be amazing thanks in advance
