I'm not 100% sure if you can, I think so. But the question is are you sure you wouldn't want to simply use a Shilan or a hart or something similar. I am a huge tikka fan, but with the cost of rebarreling, spending another couple hundred on a new custom might be the way to go. Especially if you have to buy another tikka barrel and have it reamered. otherwise I can see the cost savings would be significant. Good luck
oh, and welcome to Long range hunting. Lots of very knowledgeable folks eager to help . You might want to repost in the gunsmithing section since often times those who are really interested in their specialty will read those sections first.
