With embarrassment, I had my first squib the other day testing some mouse farts for Mrs. Mac Tm. (She isn't a shooter, but she really likes my Ruger, especially light loads). I think the problem was just too light of a load, but I'm curious what others have to say.
Powder level was visually checked each case. Charge was confirmed on 2 scales. Lee Auto Disk on top of auto indexing LCT.

Charge: 4.2 gr W231
Primer: CCI 500 small pistol
OAL: 1.45"
Bullet: Rainier Ballistics 125 gr flat point

Winchester data shows starting load 125 gr J.H.P at 4.1 gr.
