The 221 gets my vote. I have 221, 218 bee ,22 K hornet, 17 mach IV, 17 HMR, and 223. The 221 is the best of the lot. Just my opinion. The hornet brass is weak, Need high cost dies for 17 mach IV. 17 teen's barrels get durty. Some people just like what they have. Best of luck with your choices, Twyman
