I'd probably call Sierra and Alliant to see if their ballistics lab tried RL23 with the 130gr Gamechanger. They may give you some guidelines on a load.
Thank you for the advice. I bought a copy of the Sierra 6 manual in the hope that they would have this info included but although they mentioned that the 130gr Game Changer would add to the versatility of the 6.5x55 Swede they had no loading info for any of their 130gr bullets. I emailed them and was told that they haven't done load development for the 130gr bullets.
