First Squib Ever

Had my first squib load this weekend in my SP101 3". I had a batch of hand loaded 38's using 125gr Berry's over 4.5gr Unique. Sure this is a starting load but I wasn't expecting a squib. I use a single stage press and shine a light on the loading block to verify charges before seating. So I'm 99% sure it was charged.

Before the squib round the Chrony was throwing some really extreme spreads 500 - 700 fps. I thought it was acting up. I've had problems in the past with the sky screen on vs off and shaded vs full sun. I should have believed it this time.

That's too bad. I'm glad you caught it before the next round!

I've had squibs, but only with factory ammo.

whoops!!

I actually stacked FIVE bullets in the barrel of an old breaktop .32 S&W one time. They were so downloaded in deference to the age of the guns, I actually underloaded them.

Lesson learned...

My usual practice for starting loads is beginning close to the lower end. This encompases all the various pistol calibers I load for. Maybe it's just the powders I use but seems like the low end loads in Lyman's 49th are good just for sooting up my brass.

My final preferred loads usually end up near the top end loads listed in the book. Not because I'm wanting to hot rod but rather looking to match factory loads with maybe a tad extra oomph.

That bullet is easily tapped back out using a cleaning rod. But the next step is to find out how the squib load occurred. With the variation in velocities, it would seem to me that your powder measure may be throwing erratic charges, but why that might be I don't know without examining it.

Just for fun, the oddest case of varying powder charges I ever encountered was when helping a friend check out why his were all over the place. Here is the situation. Loads done on one day were uniform and correct. Loads done on another day were erratic, while loads done at one time of a day were too heavy while ones done at another time of the same day were OK. All loads were weighed on the same scale; none were thrown with a measure. Prior to rearranging his loading room, he had had no trouble.

The solution? When he moved his loading bench, he put it over a floor register. There was enough gap between the bench and the wall that air could blow up between them, be deflected by boxes of loading supplies, and come out under the scale pan. If the heat or air conditioning was on, the air blowing under the pan raised it, so it took more powder to bring the scale pointer to zero. If the heat pump fan was off, things were fine. Of course, the errors occurred with rounds loaded on hot or cold days, when the fan ran almost continuously, or at times of the day when the unit was running.

Yep that's exactly what I did. Tapped it out with a cleaning rod. I use a Redding 3BR powder measure. Its been fairly consistent with all my powders Unique, Bullseye, Power Pistol, and LongShot.

Years ago I used to carry a wooden dowel rod to the range about 8" long just in case I did have a squid round.

I just had my first one too. I believe mine had no powder. I thought it was a hang fire.
