I was wondering about using this powder in my 6mm AR turbo improved -- basically a 6.5 Grendel necked down with the shoulder pushed out and angle changed to 40 degrees.
I heard that the burn rate was too fast, but if you are using it in a .243 Win then that probably isn't true.
Too hot or not?
I have a pound of RL-10x setting around and am wondering where to safely start with a load workup using 105 gr Amax.
Any experience with this powder or ideas?
