I tried it in 65 mm hulls and it's so dense it didn't stack well. At least in straightwall hulls with SG16 or Z16.

Perhaps in tapered hulls with a 7/8th wad IDK, but I wonder if you're looking at ...

Seems like 572 might be ideal for 1 oz in 2 1/2” hulls, with the SG16S wad. Just a thought.

I've used and tested it in 65mm Cheddite hulls. It fits fine even with the regular SG16. At 1220 ...

WSF works and I used a pile of it when Winchester CF cases were common with 1 oz. of shot and the WAA16 wad. It also worked well in the Remington RGL hull with the WAA16 wad.

Mark, any thoughts o ...

I don't know whether it's a problem particular to my press, or me simply being an idiot. In any case I could not get the MEC short kit to work at all on my press for 65mm hulls. It crushed every hul ...

I can tell you that 425gr of bismuth will fit in a 65mm Cheddite hull using 572 and SG16S wads. It will go 1200 or 1250 depending on the charge, with more or less reasonable SD/ES.

If I had to gue ...

I had zero luck with the MEC short kit on my 600jr. It maxed the adjustment and crushed hulls with no adjustment left. Maybe I was missing something obvious and just too stupid to figure it out IDK. ...

Looking at the map of my upcoming sharptail hunt in ND appears there will be a lot of WPA hunting, and non-tox required.

I have 10# of Bismuth shot on the way.....

Tried as an experiment in Ched ...

were you going to try, as per MSM suggested, varying powder weight slightly in combination with a stronger? primer ?

I only have access to Cheddite primers so that isn't in the cards unt ...

Quick update. I tried 18.5 grains in the Unique load. This did not end up reducing the ES/SD as hoped. It did end up increasing the FPS more than I really anticipated.

18.5 grains Unique - 15/16 ...

Thanks for posting this. I have been waiting to see how the 572 load came out since I am wanting to do about the same. That low pressure reading gives me mixed feelings. I would like a bit higher...wi ...

Anyone care to sell me some SP-16 wads?

Some great information thanks.

Not terribly surprised it didn't work well in 1oz loadings. The 1oz load I worked up in 65mm hulls was near perfect stack height. Just the slightest compression of t ...
