Test of 3 identical target scopes using: Panda F-Class action(glue-in); McMillan Tooley MBR stock; switch barrels 6BR and 308 WIN; Fixed frozen reference scope and Field & Cave Checker.
Trial 1 – Initial with 6BR 105gr loads – all 3 scopes held POA solid.
Trial 2 – 308 WIN 168gr loads – scope #1 held POA solid, scopes #2 & #3 shifted POA < 0.1MOA
Trial 3 – again 6BR 105gr loads – scope #1 & #3 held POA solid, scope #2 shifted POA < 0.1MOA
Trials 4,5 and 6 repeated results of trial 3.
For this particular type of target scope, it would seem to be fine for 6BR, dubious for 308 WIN, and may even have suffered permanent damage (#2 scope) in 308 WIN trial.
The trials above were all shot free recoil with a 13.5 lb. rifle plus 4.5 lb. for two scopes four rings and F & C checker (18 lb. total).
Based on the above results and IMHO it would be very helpful to include test configuration, weight as fired, cartridge fired and free recoil firing as standard for future test results reporting.
