Setback in .410 tss loads

Postby Drj » Sun Jan 31, 2021 6:39 pm

Hey guys,
We did some patterning yesterday with several different brands of tss .410. Unfortunately, with reloading shortage, I’m unable to load due to lack of powder and wads, so we bought some loads. We noticed several spent wads containing 8-17 pellets ‘glued’ into the cup of the wad.
I did a search and found Why it happens, but how do you prevent this if reloading your own shells?
Loads were #9, 9.5, and 9.5x10. Cannot tell which wads belonged to which load!

Did you happen to take a picture of this shot sticking inside of wads?

I've seen it happen to cork under-shot/filler but never heard or seen this in an actual wad.

I am new to TSS, but I have experienced this when loading steel. There were a couple of contributing factors: (1) Wad fillers and (2) the manner in which wads were slit. I used to experiment, and try to tighten my high-speed steel patterns by leaving wads unslit, or not slitting them very far, and some shot remaining in the bottom of the cup was pretty common. Sometimes, part of the wad filler, especially the cork kind, along with a bit of shot would kind of adhere to the bottom of the cup instead of exiting like it should have. You said these were store bought loads, so that's your first mistake! haha. Stay away from that brand. There is some sort of wad/filler combo going on that isn't working.

My 2 cents

yeah, it happens on hot steel load too; the base of the wad does heat up first when the primer ignite (the flame will initially heat and push up the wad) then when the burning process starts and the gases expand.

At this stage, with the gases pushing up and the pellets weighing in, plus the crim resistance, the pellets tend to recede cutting into the heated up base of the wad. Once the wad is launched, it cools down and the pellets get stuck in it.

I think using a cardboard filler (or a couple), or the suggested Mica wad, at the bottom will help stop this

I've had this happen with both cork and felt that I bought from Michael's craft supply stores. The cork and felt from there are pieces that are adhered together with some sort of adhesive or glue, Emma and my guess is that this glue melts under higher pressure and temperature and let's the shot stick to it.

what I do is put a small disk of tyvek or mylar from a chip bag on top of the cork or felt wads and below shot to keep it from sticking.
