7 RM is a hot rod for sure with extreme accuracy.

I shoot the 120's at 3500-3600(depending on the barrel)with 71-72g of R#22 with a CCI 250 Primer(very important).

The 154's are shot with 72.0+g of R#25 with a WRRM primer(very important) at 3200 fps.

In the 280, I shot the 160g Sierra BT at 2900 fps, which killed deer DRT...see nosler manual loads.
