Talk:List of rimfire cartridges

Minor caliber
A few points. First, the .303 Brit, AFAIK, was never RF. Barnes lists a 7.92×57mm as a Mauser, which presumably uses the same rimmed (57mmR) case as the 6.5mm, so the 7.92×57mmR & 8x57mm IRS probably aren't RF, either. If these are European (& I presume so, being metric), the "R" will generally mean "rimmed" not "RF", so it's likely none of the "R" IDs ref RF rounds. Barnes lists a 10.15x61mmR Jarmann; along with the others, it's Berdan-primed, not RF. TREKphiler  hit me ♠  20:08, 3 October 2008 (UTC)
