A little misalignment can smear the bullet on one side. Having .432 throats and a .429 barrel doesn’t help either.
That can happen if your lead is too soft, with soft being defined by the gun. To get hardness “right” for that gun / design, cheat and ask Professor Gun what’s hard enough.
Assuming that all the chambers are aligned the same, pick one chamber, load & fire that same chamber with the other chambers empty, 6 times. Change targets. Now repeat this test on the SAME chamber with loaded rounds in the other chambers. If bullet hardness is sufficient for THAT weight (length) bullet design, then groups should be the same. If they’re different, your bullet’s not hard enough “for THAT” weight / design in THAT gun.
Your other problems can be “fixed” by sizing .001 over bore. Then using a gas check, a base protector, & a bore condition stabilizer. Oh wait, those are all the same thing! Silly me. Correct your sizing before running that test cause a smaller diameter will have some flexibility of movement too allowing you to use a softer mix.
You know, a GC could also be named a revolver correction device. Revolver Improvement Device? I'll think about it.
