So as to not hijack another thread... I have really enjoyed reading through the on-going "Rimfire Prove It" thread, and was pleased that several of the intrepid band of shooters were bringing their 22 WRMs to the party. But it does raise a question: Is one rimfire cartridge inherently more accurate than another" Certainly, the 22 LR is likely be to be the most accurate of the bunch. But then, much more work has likely been done to optimize the cartridge for accuracy. However, I seem to recall that the 22 Short has also been used a little in competition. On the other hand, I have always regarded the 22 WRM and 17 HRM as a hunting cartridges. So, how would one rate the (so-called) inherent accuracy of these four rounds? My gut feeling is: 22 LR 22 Short 22 WRM 17 HRM Thoughts?
