I bought a used .243 for my middle son about 6 years ago. Paid 150.00 for it. Very accurate. He decided about 4 years ago to buy a new Tikka 270 wsm. Well, he still hunts with the 788 and the new Tikka sits in the gun cabinet. Can anyone tell me if the 700 barrel will fit these? I don't want to rebarrel this one but I always keep my eyes open to see if I could find a fixxer upper.
