For reference - Proof Research Bolt Action Stainless Steel Blank Barrels

I bought the .284 cal, 28in, 1-8 twist, 1.22 breach option, just received it in the mail today. I was not entirely sure what the contour of the barrel was due to there being no description about that on the item page. Did a couple measurements and I can say with relative certainty by comparing with proof's site that this is the light palma contour, finish length of 28in. Hope this helps.
