Hey Mike - I figured Swiss 1 1/2F might be about the duplicate of Enysford 2F and that 2F Swiss might be a bot too "fine" for the job.

In my .50/95, 78gr. of 3F GOEX was only 70fps faster than 85gr. 1 1/2F Swiss, using the same 368gr. FN bullet.

Both powders were loaded to the same volume, thus 85gr. Swiss 1 1/2F took up the same space as 78gr. 3F GOEX. Thus, Swiss BP is much more dense than GOEX, which should be close or the same density wise, to Old Enysford?? I do not know if this is so, or not.

I did not have any 2F SWISS to test in my .50/95, but figured likely the same velocity as 3F GOEX, thinking perhaps the 2F Swiss might be faster than desired.

Swiss brand powder should be easier to obtain, in Denmark.
