A squib is just that, a round that doesn't fire. If you are getting powder ignition, & it is underpowered, not really a squib. If you are using really old brass & they are splitting, then you may not have enough neck tension to hold the bullet & give good ignition, but RD is really fast & that shouldn't be an issue in a 1 1/2" bbl. I would suspect your powder drop & there is not powder in the rounds that don't clear the bbl. The other thought mentioned is a blocked primer flash hole. IF you tumble brass with the primer out, stop doing that or inspect each case after tumbling.
