Depends, do you want something you can shoot for days and days for $30? If so go with the 22lr. If it doesnt matter to you and youre ok with buying ammo online id def go with a custom ruger 10/17machII. They are def superior to the 22lr
I have both a single shot mach2 and a ruger 10/22 converted mach2 and both put big cracks or holes in the side of the ammo cartridge after being shot. doesn't effect accuracy but it is definitely weird.
