To put the question to the group - one of the rifles I'll use in the centerfire shoot will probably be the .220 Howell I bought from Joe Darby. It's a single shot Nesika action with a straight tapered barrel and single set trigger. I consider it pretty much a varmint rifle - any one have concerns about calling it a "sporter rifle", compliant to the rules? I'll use something slower for the steel shoot, as the .220 is probably exceeding the 3300 fps limit.
