Can't wait to hear how RL15 works with your rifle. I haven't heard of many that didn't like RL15. It is almost tailor made for the Whelen shooting 225-250gr bullets. Mine likes 60gr of RL15 for the 225gr TSX and 59 for the Speer 250. What rifle are you shooting? Scotty
How is your load work coming Coop? Looking forward to seeing and hearing about your loads with the 225gr AB and RL15. Haven't heard of many rifles that didn't like them. Scotty
