Brent, don't think I'd say "squibb" outright, but those could be "flamers" MAYBE if your wad column is not sealing properly....overbore?....weak nitro card?...long forcing cone?.....hulls shorter than chamber?.......thin plastic hulls?

Would not worry about weak crimps, would not contribute to blow-by and torching wads?

Just a thought,
Mark
