If anyone on this forum is interested. I am selling my RSI Pressure Trace and related software as well as the TC contender I was going to use for comparative pressure testing. Included: RSI Pressure Trace module and software RSI Shooting lab software Thompson Center G2 Contender with 4.6" test barrel chambered in 10mm Auto The gun has less than fifty rounds through the barrel and the pressure trace has been used once. The original strain gauge has been destroyed when I removed it from the barrel, however new gauges may be purchased from RSI. I do not have the money necessary for the ransom rest and related equipment to really get the project going. If your interested in the quest for personal ballistics testing PM me for more information and price.
