Anyone shot out and sectioned a Proof carbon Sendero or Sendero Light contour barrel? I need to know how much the stainless steel steps down at the chamber end where the carbon starts, so I can work out how close I can run my chamber shoulder to this point. Proof are being coy with me on this. I don't want to know the whole SS liner dimensions - I'm not in the slightest bit interested in trying to copy a Proof or any other carbon barrel. I just need to know how much it steps down from the 1.200" OD at this point!
