Swiss 3fg

[Steveu]

I have been testing some Swiss 3fg that I have in the 40-65 with greasers and it’s been working great.
My question is, have there been any issues with lots that were produced in 22,23 or 24? The partial can that I have left I got in 2018.

Cheers,
Steve

Steve,

I use 3F Swiss and 3F OE in the .38-50, 40-65 and as well in the .45-90. I have not seen much difference in performance after a little load development with a new lot of powder in either brands like I see with the slower 1.5.
I always go through the ladder loads with a new lot.
The 1.5 Swiss has given me some problems on and off more than the OE.

Thanks for the info Kurt.
