I have a R-93 in 7STW that will do 1.5" 5 shot groups at 200 yards with doubletap 160 gr accubonds. It is shorter than a bolt action and the weight is just fine for hiking around AZ. Good luck.
It is a great caliber. I have 3 rifles in this caliber and they all shoot great. I reload for the Sendero and the other 700, but not for the Blaser. Check out the post in this section if you want more info on the caliber.
