Big fan of 58 with patched roundball for hunting, though I prefer a shorter barrel than many (well under 30”) and use powder charges of 3F Swiss in the 80 to 90 grain range. For me, the fun goes away with heavier charges.
With a roundball, I like to sight in at 85 yards, giving me a point blank aiming out to about 100 yards, with POI less than 3” above or below aim point. Believe the 80 grain charge pushes the roundball over the chronograph at about 1650 fps, and zeroed at 85 yards is about 2.5” low at 100, drops to about 9” low at 125 yards, around 18 low at 150 yards and about 4’ low at 200 yards, at least the last time at ran it through its paces at the range. The challenge much beyond 100 yards is knowing the near exact distance to the intended target.
And by the way, I would choose the Hawken.
