HadenWest - the total drop of 300" actually means nothing. One merely sights for the exact range one is shooting, when shooting silhouettes. After that, it is sight picture, breathing, triggers squeeze and follow through & LOTS of practice at those ranges - then the hit #'s increase.
The military loading of 70gr. rifle powder and a 500gr. RN bullet in a .45/70 actually has a trajectory of over 45 feet mid range to the 1,000 yard silhouettes - yet some guys, the masters, hit over 80% of them using similar or even lighter powder charges of 60 to 65gr.
The engineers said the Billy Dixon shot was impossible - yet it happened - yes - even Billy said it was a 'Scratch Shot'. Can't quite remember - 1,355yards seems to ring a bell. Seems the engineers math said the bullet wouldn't go that far - the Sandy Hook trials of the 1880's showed a .45/70 issue load with 500gr. bullet had a max range of around 3,500yards, and over 2,500yards with the 405gr. At those extreme ranges, the 500gr. bullets still penetrated over 9" of solid pine, when tests proved that under 1/2" penetration on pine was enough penetration to kill a man or fatally wound a horse.
Are these hunting ranges? No - they are 'target shooting ranges'.
