Great thread and thanks for the report Charlie. Also some great information from Nifty-Two-Fifty, although I think I at a minimum parallel FG's sentiment that there's some horse-schitt not necessarily worth shoveling. You mileage, experiences, and needs may differ.
That said, I still need to get my CZ-452 .17 HRM out and find it's best ammo, hence my interest and appreciation for this thread and the thoughts and information provide.
Happy (almost) Easter gents.
