I would give Chuck MacIntosh a call
http://macsgunworks.com/default.aspxTaper is all about weight.
You said you wanted a non-designated Savage action with a Accu-trigger.
Is there a reason for the Pac-Nor choice?
Chuck has a good brake as does Darrell Holland.
I have more of those two than anything.
So you want 16 inches of actual barrel before the brake?
What bullet do you want to use the most?
