Im shooting a Tika 204 Ruger that has been a very good varmint rifle for me and is super accurate. I have about 1000 rounds through it now and it's still working great. I was thinking that if it starts showing signs of getting tired I might rebarrel it to 25/204 similar to a.257 Kimber. Has anyone tried this or does any one have either and how has it been for you. What are your thoughts on a 25/204 or .257 Kmbr doing double duty as a varmint/deer rifle ?
