I'm thinking about a bolt gun for NRL22 matches and these two are within the budget and both seem to be on the better side of performance. Currently using a Ruger 10/22...well the receiver is still a Ruger; Green Mountain barrel, Kidd bolt, Archangel stock, BX trigger. I just got rid of a Ruger American Rifle Target for feeding problems, extracting problems and so-so accuracy. So, would like to try a bolt gun again and am wondering how these two might work. let me know your thoughts and/or experience related to the Tikka and CZ 455/457.
