I'm just getting started into chambering my own rifle barrels and have only used reamers for rebated rim calibers. I have a friend that wants some work done on his Remington 700 chambered in .220 Swift and was wondering that since this caliber is a semi-rimmed one is there anything different that has to be done to the chamber because of the rim or is it just a difference in the bolt head and or the extractor?
