Re: 1,100 yard shots
The Whitworth was an exceptional rifle and a great example of the fine tradition of rifle smiths in Britain. It was certainly capable of that kind of accuracy in the hands of a skilled rifleman. During the American War Between the States, many Whitworths were employed by Confederate marksmen and with the rudimentary telescopic sights of the time it was considered to have an effective range of up to 1,500 yards.
Let not the rifles of good and free men be reforged into plowshares, but may they rest in a place of honor; ready, well oiled and God willing unused. For if the price of peace becomes licking the boots of tyrants, then "To Arms!" I say, and may the fortunes of war smile upon patriots.
