Hornady 129 grain Interlock SP and RL-15/Varget Load Recipe

[VASCAR2]

You can use Varget and RL-15 in the 6.5 Grendel but you won’t get very good velocity. The burn rate is to slow for optimum useage in the 6.5 Grendel size case. I don’t use standard small rifle primers in the AR-15 because of the floating firing pin design. The Federal GM Match AR primers are gtg as are CCI 41, CCI 450 or BR4 and Remington 71/2 Match primers as they have thicker cups.

The current trend for temperature stable powders in the 6.5 Grendel are AR Comp, H4895, IMR8208XBR (I use it for lighter bullets).
