Any thoughts on other hunting bullets I should consider?
I probably would go with a 140g Sierra Game King and work up loads with RL-22. I think you're rifle will shoot better than the groups you are getting so I would suggest the Sierra's and a powder that is known to give good groups. I have a Sierra V manual and can give you load data for that bullet if you need it. The loads are for the M96 Mauser with a 29" barrel but with you're modern chamber you can go above the loads listed. At least it gives you a good starting point. Also if you do a site search for 6.5x55 members have posted loads that have worked well in their Savage based Swedes.
