this is going to be just for deer and antelope. I have a 300 win mag and a 300 rum. I got a deal on the rum thats why i have two 300s. Both tend to do alot of damage to meat if i take a quartering shot. I try to limit my shots to around 300 yards and figure both of these bullets will hand that well. Whats going to be the best choice. also will i benfit much with the wsm or would a plain old 270 be just as good.
