I have one of the Canadian supplied Ross Rifles and want to reload for it. From browsing on some of the Canadian Boards, I understand that the earlier Ross Rifles like mine had a tighter than .312 bore , actually closer to .309. I have shot a few .303 British surplus rounds and it was very accurate. Does anyone here load for one and which do you use, .308 or .312 bullets? Any loads that worked well for you?
