900 Yard Shot "” 243 WSSM 105 A-Max "” Really Small Target

One of my shots last week on a really small target at 900 yards. This was my second shot. My rangefinder couldn't give me a range so I dialed up a 1,000 yard shot. Dallen on the spotting scope called the shot. I dialed in his correction for a 19 MOA total adjustment in which Strelok Pro tells me is right at 900 yards. My equipment for this: Browning A-Bolt Stainless Varmint in 243 WSSM, Vortex Viper PST 6-24x50 SFP MOA rifle scope, EGW 20 MOA rail, 105 Gr Hornady A-Max bullets and Strelok Pro on my Android phone.
