John, I tried 46, 46.5 and 47. 46.5 provided the best accuracy. This was an OAL of 2.78 and BR2 primers. I have had fits getting consistent accuracy with the 180s. I've used 8208, TAC, AA2230 and now Benchmark. Occasionally get good results, then inexplicably they (I?) shoot terrible. If these shoot well a couple of times I may use them for elk and Deer this fall.
