I'm currently working up a load with 95gr BT's and 95gr Berger VLD's in my daughters 243Win. So far it's looking pretty good.
I have used this powder with my 375 Ruger under 300gr TSX's. I have also used it with 180gr BT's in a 300WM and 180gr Accubond's and 200gr Partitions in a 30-06. Basically any where 4350's works so does RL-17 and good at that.
An interesting side note... The fired cases are very very clean, no black residue, still can see the brass deep inside. This powder is quite interesting.
