I can now capture the bullet at the muzzle - almost as if it is stopped there...

LOL... you must have photoshopped all the muzzle flash out of the freeze frame ?

You can push and pull it out. Not many get those kind of options

Squib!

Note to self: 3.2 of N320 is not enough.

Bump it up to 3.21
That'll fix it.

Might need a touch more to get it past the second port ...

Next round should push that one out. Doubt it would register MV on the chrony but your SD would be single digits.

Ganderite, if the barrel had not been ported do you think the outcome would have been different like the image below? I shoot a lot of light loads in my Glock .40 and other handguns and never had a problem. "BUT" I do not have any vented barrels.

If the barrel was not ported, it would not have dumped that last little bit of pressure that was needed. If it was 1/2" shorter, the shot would look like your cartoon.

I was using a new (to me) non-canister powder, and what I do for such things is start with a survey of loads, hoping to find a reference min and max load. I loaded 3.2, 3.4, 3.6 & 3.8.

You can see what 3.2 looks like. 3.6 was very accurate in 4 pistols. 3.8 was also good. max is probably going to be around 4.2, but I won't bother checking. I have a good load for punching paper at 3.6

Last night I cranked out 2,000 of them.
