Currently shooting 139 gn Barnes lrx. 45.5 gn of RL17, cci 200 primer, Hornady or Norma brass. I had a Barnes rep tell me you can use IMR 4350 data straight across for RL17. Barnes now gives load data for RL17. Alliant also has load data on their site for commom style bullets and weights. I have never tried RL17 with Accubonds.
