I have never had a blooper with RMC hulls and when loading C&F wads it is a good idea to apply 40 lbs. of wad pressure. RMC hulls use either 1-piece plastic wads or C&F wads and 209 primers. I use oversized (1 gauge) OSC cards to contain the shot and run a light line of glue where the wad meets the hull. Also a clean hull mouth assists in OSC containment.
