I just got one and have been running the Hornday 200 Interlock and the 185 Barnes TSX.
And I have been running TAC. I will retrieve my load data and post it. Hoping some other will do the same.
My RCM accuracy is certainly acceptable, but I am going to bed it ASAP. And for having a good bunch of semi-custom LH rifles, I really, really like this little Compact Magnum.
