A friend has asked me to load for his 223 WSSM. I do have my FFL 06 and know the law. I have no experience loading any .22 caliber, much less a WSSM. He's shooting it out of a Browning A-Bolt, and I'll have to check on the twist Browning uses.
Any suggestions for powers and powder/bullet combinations? How much overbore is that short, fat cartridge, anyway?
