I have a CZ 452 Varmint in 17HM2. It shoots fairly well, but I've been disappointed in it compared to .22's that I have. The way it was shooting I was feeling somewhat like it may have been the ammunition. After reading a post on here a few days ago regarding run-out of some Eley .17HM2 ammo I decided I may wanna try a .22 barrel on the sucker. Anyone know where a guy could get a relatively low priced take-off barrel in .22? It wouldn't have to be a CZ barrel. I could re-thread, and re-chamber it if need be.
