Planning on a 400 yard coyote rifle and wonderying why a fast 3900fps 55 gr. Nosler Ballistic tip from my 243 would be just fine? Seems that it has a plenty flat enough trajectory and the speed helps with wind drift. I don't want to use the high BC bullets because I have a good number of regular 243 hunting bullets. Maybe when I cook this barrel I will rebarrel with a faster twist but for my coyote shooting 300 yards is a long ways.
