Hi guys. Spoiling myself for my 30th this year. Looking to get a new .22lr. I shoot at a range and go out for the bunnies. I want something that would sit halfway between the two disciplines. The rifle that has caught my eye so far is the CZ 455 heavy barrel with the thumbhole stock and also the new CZ mini sniper that will be making its way to the UK in about July/August time. So the question is, will a 20 inch barrell be more accurate then the 16 inch? Up at the range I am hearing all sorts of arguements for and against both lengths. Weight is not an issue. Im a lump of a bloke and used to compete in weightlifting/strongman/Judo so the difference of a few pounds changes nothing. I want accuracy facts! Thanks in advance guys, Tim.
