This very potent round is extremely accurate and consistent. During development, we struck virtually the same spot on a man-sized steel target…at 200 yards! Customers report consistent 1″ groups at 100 yards. Safe in all strong actions including modern lever guns, modern Sharps, High Walls, and single shots.

I ordered a few of those shoulder killers last night, along with their 400 gr sp and some of the 300 gr goldilocks loads.it is over a dollar a round. Keep the empties for possible future reloading.
also keep in mind the Hornady cases with the FTX bullet are shorter to allow for their bullet. You might only want to load FTXs in those cases and leavve your others long.
