I’ve owned both in 243 and I don’t shoot anything heavier than 100gr. I still have my T3x Superlite.

There is no comparison when it comes to which is “nicer”, the Tikka hands down. They both shoot well, the edge going to the Tikka because it basically shoots everything well.

I had the RAR with rotary magazine and it worked, but not very smoothly. It’s cramped vs the M+ magazine offered by Tikka. The 6CM and newer magazines should give the OAL nod to the RAR.
