Today I shot some of Spiff's reloads (done for my rifle). First pic is my best group today with 168gr FGMM. The second is my best (and only group) with the custom 175gr loads. These were at 100 yards with little variable wind (at most 5 mph).
Obviously POI differs between the loads but I'm pretty impressed with the change. These groups were shot within 5 minutes of each other.
