I bought a variety of the bolt action barrels. I'll be able to use them in specific uses on smaller tenon actions such as the Howa mini it cz 527's. possibly 1" tenon Winchesters too. Unfortunately they're a 1/4 pitch off (metric) from screwing right onto Tikkas. I picked up two sets of double tubes also in 6.5x55 and 222 which has me thinking or an interesting double with interchanging barrel setup. Very light profile on them and it seems they'd make a real nice handling rifle.
