I tested my 18" benchmark barrel 6 creed last night. 41.5 @ 2850 with alpha brass was definite max - heavy bolt lift and some brass flow. I will back off to 40.0-40.5 and shoot until the barrel is broken in/sped up.

What about an Aero Solus? Have not tried one, but they have prefit options and a lot of features for about as cheap as any. Weight might be a draw back, but the $400 savings might allow you to save weight elsewhere?

I always tumble after sizing to get lube off. In my early days of loading, I had an action start to show early pressure signs, when my gunsmith tore it apart he said the one-shot was fairly caked in there from not cleaning it off brass well enough.
