I know but I still have a few pounds of the stuff.

Unique is alot closer to 7625 ( Universal is probably closer yet ) than Green Dot . GD is a fairly fast powder

Give him a call he will tell you what he wants . He will also make suggestions for your load if you need it . Super guy.

Thank you Mark!!

Angel - I have 2 bismuth 16 ga loads listed on a spread sheet that I look at seriously but have yet to try them - both use Longshot and give low pressure. If you wish I will PM them to you. Again I have not tried them and can make no recommendation as to effectiveness or safe pressures.
Given the serious shortage of low pressure non tox for our older guns I also look to this thread to shed some light on options.

For those who do load bismuth do you drop the shot according to the charge bar weight indicated? For example if the recipe calls for 1oz. of shot do you use the 1oz. bar or must you add or subtract shot according to weight?
Thanks

Eric. please do, thanks a bunch!!!
I got the reloading bismuth book from PR and they advice to weight out the shot. The 1 oz bar will not give you an oz of bismuth. The same thing if you have a loader that uses bushings. It has to do with the density of the shot, I think...
