FOLLOW UP: October 12, 2024. H4895 with 20.8 grains. From the above 20" SSK TC averaged 1081 fps. SD: 21. Last 3 shots were basically in the same hole at 50 yards. This will be my go to subsonic load for short range whitetails here in Michigan. Hodgdon posts 19.7 grains of H4895 - as always, proceed with caution.
