Most guns will operate well with 1.3 grains of Bullseye.
Be very careful when charging the .25 Auto with powder, as only small powder charges are used and a double-charge can be easily overlooked.

Even 2/10 of a grain can cause velocity to jump 200 fps, with a big jump in pressure too.
I use 1.1 gr. of VV N310. It's faster burning than Bullseye by about 15 %.
If you need a case trimmer I have several dozen of them from when Lee used to make them in .25 ACP. Still on the card. $6 shipped.
