I have recently just became interested in Tikka's because of the excitement they seem to generate here and other forums, that and I have been singularly focused on trad archery. Therefore I don't really know much about them other than one action size and relatively easy cartridge conversion. I have a Varmint .223 coming that I hope to shoot 77 TMK for the short term and possibly having rechambered in .223AI. The reading I've done indicated that mag length will prevent loading that bullet as very long, but my question is what about a standard length Tikka mag, does the bolt stop prevent that from working? I'm sure I'll have more questions.
