Home Forums Reloading Big Game Rifles 6.5CM...which projectile? And what powder has given best results with each?

I am currently working up a RL17 load for the 130 game changer. Hit pressure before I was even close to Sierras published max. 41.7gr gave me close to 2900. Sierra lists 43.3 as max with a mv or 2900. 43 was 3080 with some nice swipe marks. Out of a Kimber Montana.
