My son took his 1st deer on the last day of the Pa youth hunt using the .223 and 64 bsb also. Mature doe at 145 yards broadside, shot through both shoulders and exited. Deer went straight down and never got back up. My son later asked me why I bother with any other cartridge since the .223 with the nosler solid base is more than enough?
FWIW I've taken 2 buck with this bullet also. One heart shot and ran 20 yards. The other was quartering away at a hard angle and hit at the last rib going in and exited out the front, deer ran about 50 yards.
Seems like this bullet is a proven PA deer killer then!
Thanks to everyone for the pats on the back. Rifle season is up next and we have 3 tags to fill yet (a buck tag for each of us, and 1 more doe) so the best could be yet to come.
