blackhorn 209
Any idea what my velocity would be with a 300 grain barnes expander pushed by 90 grains of blckhorn 209. Would I get the same velocity with 90 grains of pyrodex. Finally what would my bullet drop be at 75yds 125yds and 150yds if I'm dead on at 100yds.

1687 = 80 1892 = 100 grains of Black Horn with a Barnes 300 grain Expander. So if you can find the BC of an expander, you can run it through a ballistic calculator with the kind of sight in distances, etc you want.

I got this. 1" high at 50. 2" low at 125 and 5 inches low at 150. Recommend you sight in 3" high at 100 yards, if you do that your good out to just shy of 170 yards by MPBR.
