RE: .243Win. loads
I havent used the smaller bullets yet due to me spending my time working up a deer hunting recipie, but I have used 100 grain hornady interbond with 40 grains of 4350 for a MV of 2900 to 2950. Pretty consistant. The other I have been using is BLC-2, 38 grains with the same bullet. BLC-2 is a faster powder better suited to smaller grain bullets, so you might mess with it. I havent clocked the BLC-2 yet. EJ
