I have a Custom 12" 22 K-Hornet for my Contender, and just recently I converted my Ruger 7722Hornet to K-Hornet. Accuracy increase is the single major reason to do the conversion with extended case life a close second. Ease of fireforming and the increase in velocity are just 2 other benefits. I am very pleased with the K Hornet, it just can't be beat. Whenever I take these 2 guns out, people seem to shoot them alot!!
I like this cartridge.
(If you have this conversion done, and you have 2 seperate guns, be sure to keep the brass for the guns seperate. Sometime the gunsmiths just can't get the chambers to match. We tried on mine,but there were issues).
