I found this load using Nice shot( whatever that is) on the 16 ga forum:
Federal hull cut to 2 1/2"
Win 209
SG 16 wad
7/8 Nice shot
6 fold crimp
1107 fps @ 7280 psi

Aaron, yeah I think they are measuring it by volume.
This non tox loading is all new to me.

If there is anyone interested in pooling resources to get a 7/8 oz bismuth load worked up, please pm.
I would like to start with some of the most common components including rst once fired hulls, gulandi 16 wads and the cheddite cx 2000 primers we all bought up this winter. powder currently in production.

science-but not rocket science.

Mark,
The GD load you posted looks very good depending on how it patterned.
Roll crimp?
Jim

I downloaded a spreadsheet from the 16ga page some time ago. They list a few bismuth loads. Only one is what I would call period correct.

Fiocchi 16 hull 2.5", Fiocchi 616 primer, 22 gr Long Shot, SG-16 wad, 7/8 ounce bismuth, 1250 fps, 7800 psi, source BPI.

Guys this is probably another thread topic but certainly in line with what we’re discussing. I hand load 2.5” 16 gauge shells, no press. This means I prefer to roll crimp. I prefer this because I weight every component and just like the way roll crimps look. Kind of like why I tie flies for fly fishing. Through my research it seems the general consensus is that roll crimps reduce pressure as compared to a fold crimp. What’s every one’s opinion of replacing a fold crimp in a recipe with a rolled crimp?

As you said, beautiful shells, but time consuming. Benefit is that it supposedly lowers pressures. I could do that for hunting only, but too much time involved if shooting targets.

Here is a load that looks good, and maybe that first load from BPI is accurate:
Cheddite 2 1/2"
7/8 oz Bismuth
SG16 wad
CCI 209 primer
Longshot 19 gr
1100 fps and 4700 psi
Tom Armbrust tested

Duck hunting often involves cold weather, I am not sure I would trust a load at 4700 psi to not squib on me when there is duck in range.

Good point Pete
