Too late for the poll, I guess.
I was hot to go on one when I read about it in the magazines of the time.
Lost interest at prices wanted for the ammo. The minor issues with semi-autos (one major draw was that I could slide a new barrel onto the 10-22, in theory) reinforced the lack of draw.
I can shoot 22 rimfire for volume on the cheap, and handload for higher performance, when I want to make the gophers fly, with my .223.
Been pondering a 17 Ackley Hornet, though, to get better than HMR performance on about the same money.
