If you feel compelled to stay away from the 65 grainer for any reason the Sierra 63 gr. SMP is an outstanding bullet ( the only Sierra bullet I'll use on anything bigger than varmints) It is indeed the "short/fat" and will stabilize in a 1 in 14.
Heard good things about the 65 GK but have never used one, so no help there.
This #275 pig fell to a 63 gr SMP..
