OTB today is the Model 340V (.225) Customer is looking for a cleaning, new magazine, new bolt and functions test of the weapon. Definitely gonna make a few jokes.
Great Question, I spoke with the seller beforehand and asked them what weapon this came from and they let me know it was an exact copy of the weapon I was working on. I took their word and got lucky. But if there was another weapon with similar ammunition, I would use the following: pacifictoolandgauge.com/saami-centerfire-rifle-headspace-gauges-nopix-/11609-225-winchester-saami-headspace-gauges.html
