In a letter to the Howells' recounting the heroic exploits of John T. Lewis, Twain wrote the following:

Lewis,the prodigious … saw the frantic horse plunging down the hilltoward him on a full gallop, throwing his heels as high as a man’shead at every jump. So Lewis turned his team diagonally across theroad just at the “turn,” thus making a V with the fence. Therunning horse could not escape that, but must enter it. Then Lewissprang to the ground and stood in this V. He gathered his vaststrength, and with a perfect Creedmoor aim he seized the gray horse’sbit has he plunged by and fetched him up standing!
What is this "Creedmoor aim" he refers to? Is it a reference to the Creedmoor rifle range in Queens, New York? https://en.wikipedia.org/wiki/Creedmoor_Rifle_Range
