[QUOTE="tacomHQ, post: 2071911, member: 67159"] Machine a piece of Graphite 2+" long x bore -.010"- light sand blast on the body . Seat it into a piece of brass. This black body is extremely reliable for IR gun use. IR guns are very picky for what the surface reflection/specular finish is. Fire your string chamber the Graphite round weight blank time and pull it with immediate measurements. Without cringing- a piece of aluminum- sand blast- wrap with tape/shrink wrap every 10" or so to protect barrel and center it without direct contact- insert and heat soak it as a base value and trend guide. A long enough rod will allow you to push the rod into the action from the chamber getting a read- or any value along its length. Crude but a reference. [/QUOTE]
