Quick Range report for you: Hornady American Gunner 140GR BTHP has been my load of choice for my B14HMR for the last 600 rounds, overall I really like the round and think it is the best bang for my buck. It generally shoots between 1MOA and .75 on paper at 100 yards.
Usually out of my B14 my MV is average of 2630FPS. With this MV my dope for 1008 yards is usually 9.7 mils of elevation.
Yesterday I was out shooting 1008 yards and noticed that most of my rounds were going right over the target with my 9.7 DOPE which had been dead on during several previous range sessions at this very distance/target. I was perplexed and after some time we re chronographed the ammo. This was a new 200 round can that I was shooting and we determined that average MV was around 2700 FPS or nearly 70 FPS higher than my previous lots of the same ammo. Once I adjusted my kestrel with the new MV my dope showed 9.4 mils and I was again dead on at 1008 yards.
Just wanted to share in case this helps anyone. Curious as to your thoughts if maybe you have had similar experiences. The lesson for me was to re chrono if I start to see consistent changes in elevation in comparison to previous dope. Ultimately I still really like this ammo but this was a learning experience.
