I've shot literally hundreds of these loads with no problems and good accuracy.
Dacron works well for this application as dons and others have said, just enough to fluff out and hold the powder in place to the rear of the case.

This is true or worse,... like a blown-out case head.

In straight walled cases, like the 38-55 or 45/70, cornmeal or cream of wheat just add to the "projectile weight".

In bottle neck cases, particularly more modern types, the corn meal or cream of wheat can actually pack into the case neck on ignition and create a bit of an obstruction. Then even reduced amounts of powder can develop dangerously excessive pressure.

When working down in performance below book recommended levels, the same level of care must be taken as if you were working up above book recommended levels. JMO

The load in question is a 32 Winchester special. I have the Lyman 49th book and the load data for 3031 is 28g for the low. I'm using 26g and it fills the case to the curvature of the neck. It has just a little wiggle room. Is it enough for concern about using a filler?

If you get down to a half filled case, I should think the type of ignition you would get would depend a lot on whether the gun is pointed up or down or level when fired. Sounds like it could get dangerous if you tested the load level then pointed the gun up and pulled the trigger.

Back in the 70's prime skinned and stretched coyote hides were bringing up to $150 and a Bobcat hide over $300. We were shooting reduced loads in 22-250's with a 55g FMJ and trying for one little hole in and sometimes out. The goal was for just one in. Lost all my load books for that era but we were doing pretty good at it that winter. Heavy snow and good results calling in. Some chase work on snow machines after a shot but we tried for broadside heart shots at under 200 yards. Between my brother, his wife and myself we shot 120 dogs and 6 cats that season in Montana.
