The difference in pressure is because of the hull length and the use of soft filler wad.

Here is the information sheets from these two loads. I did individually weight out the powder and shot for these loads.

I've never understood why a shorter shell produces more pressure. If it does simply because it's shorter and that's the only difference, please explain why.

I have duplicated this Bismuth load in a Remington hull with a cork filler under the shot and I'm going to send it in for testing. I would think with a roll crimp that this should have lower pressure like Victors 2 7/8" load. I will post the results when I get them. I'm looking for a goose hunting load for my lifter, that is why I'm going with #2 Bismuth.

Not likely. The tested loads are not identical, the 2 5/8" load used a Cheddite hull, the 2 7/8" load used a Remington hull. I will wager use of the same hull will show closer results in pressure.

I look forward to seeing the results. The roll crimp is now the only significant difference from my load. Pressure should drop. Perhaps even below the pressures I produced. -Victor |

Also with the testing I had done using TSS , which always required the use of fillers , the more soft fillers ( felt , cushion wads ) = lower pressures and less consistency . As opposed to harder filler ( Nitro cards and cork ) = more pressure . But don't take my word for it you can always call Tom Arburst , he can explain it better than me. |

Well, I'll have to call Tom. I don't see where there is less space for gas to expand. Yes the shell is shorter but that's because less space was used in the wad section not the powder section. I could see what type of wad or how deep the crimp was would effect pressure. After the holiday I'm gonna have to call him.
