    Has anyone any knowledge or data about this new alliant powder? It seems to fall in the Leverution, 8208 xbr category. Chas

      I've seen the Power Pro Varmint and the Pro MR(Medium Rifle). I thought the Varmint may be in the X-Terminator range. Don't know about the other.

        I spoke to the rep at the Shot Show in January. It has a burn rate similar to Varget. That makes it a little slow for the Grendel.

          AR-comp is a reformulation of RL-15 to make it more temp and velocity stable.
          Alliant is introducing a new extruded powder, AR-Comp. AR-Comp is an advanced re-formulation of Reloder 15, a double-base Bofors powder. There are changes to internal and external chemistry to provide much better pressure/velocity stability across a wide range of temperatures.
