Home Forums Hunting & Shooting Long Range Hunting What would I need to do to make a Tikka t3 in 6.5X55 into a 6.5 x 284?

Technically, the 6.5x55 has a larger case head, but the bolt face on the Tikka is the same regardless. And Lapua is the only one making Swede brass with the larger case head, the others use standard .473".

That being said, yes...a 6.5-284 reamer would clean up a swede chamber. I would not go down that road if your swede is a shooter though. You don't gain much. Might as well shoot out the swede and think about options when time to rebarrel.
