Im not one to really get into ballistics and have a 39 gr. BK load and am wondering if these POI and drift sound right? My load is the following. Im not looking for super precise number but something I can use on coyotes which are big targets.

39 gr. Sierra BK
25 gr. Benchmark
Fed 205 M
3490 fps (approx)


Drop
100 yrd 1.78"
200 yrd 0
300 yrd -7.61
400 yrd -23.77

Drift 10mph / wind dir 90
100 yrd .78"
200 yrd 6.18"
300 yrd 14.41
400 yrd 27.68

Im using the program on Handloads.com/ ballistic calculater. If these sound way off could I send my info to one of you guys who know how to properly figure this out.

Cheers!!

Both of these agree with each other....at least withing one tenth of an inch at 300 yards.
