What happened to keep this cartridge from becoming a success? When it was introduced, I hoped to see used firearms pop up at the gun show and shops ready to be snatched up. My dreams of finding a used accurized 10-22 in 17hm2 are over. I thought that small varmint hunters, squirrel hunters, etc. would have appreciated the flat trajectory compared to the .22lr. So what was the demise of the cartridge? Cost vs 22lr? Large strides made by air rifle manufacturers? SGWGunsmith started a thread on the Ruger mark2 having problems with the recoil impulse. That certainly was a factor. Easy for me to say, but that seems like that problem could be have been corrected. The newer Savage a17 (17hmr) sounds pretty reliable these days as an example of technology and know how overcoming problems of 17 caliber rimfire cartridges. What say you?
