Remmy, Sounds like you have everything you need, I shoot a lot of steel out to 1k with a suppressed 308 and my load is Lapua brass, CCI BR primers and 44.2grs of Varget under a 168gr A-Max. I think you will do better with the heavier bullet over the lighter 150-155 grainers.
Great thing your doing by helping others get into the LR thing.
