After reading Warren's reply to a post it caused to to remember my latest venture beyond my personal experience/training envelope. I thought I'd share it with everyone here and would also like to hear some of your's. Some of you recall my recent endeavour to shoot 1 mile. Many of you know I'm a first round hit kind-of-guy and I figured I'd use my then-current knowledge to accomplish this task. I assembled a little computer program for use in this task and had tested it extensively at distances to 940 yards with adequate success. The rifle I elected to use was a Rem 700 custom chambered in 338 RUM using a 300 Sierra MK. My first shot at beyond 940 yards was from 1197 and it went very well but the rounds impacted a little high (4 inches on the cold bore and then 20 and 22 inches on the two subsequent rounds). I was a little disturbed by the 21 average inch elevation problem after cold bore. When I backed up to a little under 1760 the rounds impacted more than 36 inches high in all cases. I went home and reexamined the events in an attempt to understand the problem(s). I'm still not ready to try the 1 mile first round hit scenario but I'll give it a few more attempts this Spring and Summer. It had been a long time since I completely missed the entended target with all rounds but that first 1 mile attempt was a real eye opener.
