Yes we find the maximum number of decent shots is 20 from the 8 grm, and the black rubber seals expand immediately you take off the end cap to put in the new capsule. All my CO2 pistols now have 90 degree Shore A polyurethane seals in as I buy them in bulk. The Crosman 600 seal fits a lot of different pistols, but not the Challenger which is larger.
