ROB F 60 shots you have not run in the barrel with the pellet lube .
It took 2 tins of pellets to run my ftp900 in to small group at 55yds and it is still bob on 6 tins latter .
It took about the same to do my GC2 in 1988 and it ran one hole groups at 50yds for the 5 years I had it and I never cleaned out the barrel in that time just ran lubed pellets all the time.
Just in case you think I was a nobody my real name is .
