Yes, that's almost exactly my deer-hunting load in my older CVA cap-lock .50 caliber Hawken-Carbine with a 24" barrel (6� lbs) using a .490" Hornady swagged, rifle ball with a .016" denim patch lubed with a soft, but fairly solid mixture of bee's wax and Crisco Vegetable Oil and a load of 70 grains of Swiss FFFg.
I limit my shooting range to 80 yards or less... and, at that range, this load shoots through BOTH sides of most deer and is very accurate... usually putting 2 outta 3 rifle balls in a smallish figure "8" hole with the 3rd. shot nearby or touching the other 2 shots shooting off the bench-rest @ 25 yards.
The rifle and load are very accurate. Almost any variation in the bullet strike is usually caused by my old eyes using iron sights.
Strength & Honor...
