i decided to tear down 20 rounds that i made up with gas checked boolits. in 16 of the 20 i tore down, the gas check remained in the case neck (300 win mag). somehow, i need to get them out. the 2 ways i can think of is 1) try to push one side in, cocking the check sideways (the risk there is it may very well fall into the case). and 2) drill a hole in the check, and try to dig it out that way. the 2nd idea seems rather dangerous to me (risk of the powder igniting). is there a time honored tried and true way to get these out without getting hurt?
