Gas checks on Lee APP

[asmith80]

Has anybody tried sizing a gas checked boolit on the Lee APP? I just ran a few hundred 9mm boolits through mine, but since they were plain based I didn't have to worry about anything except keeping the tube full. Just wondering if there's a trick or anything I need to watch for with gas checks and running them through the auto feed system on the APP

I sized my checked bullets just fine. My checks are a snug fit on the boolit shank. I seat the check on fully before I size.
Other than that no real issues.
