It's a good book. The X-ray shots are handy. Take your PH's guidance over all. A lot of them will not let you take frontal shots and hard quartering to. Especially on some animals like wildebeest where if you make a mistake...it's a LONG day.
Broadside, anything on the shoulder is going to be a dead animal with 300 PRC. When in doubt, just hammer home to yourself "on the shoulder." Shoot them there you'll break the shoulder, possibly clip the top of the heart, and destroy the lungs.
When I say take your PH's guidance over all, it's important. My kudu was 45 degrees quartering away. He told me "right behind or on the first stripe level with the shoulder." It was a 100-120 yd shot. This was the result. Went 60 feet and thud.
