Not arguing over this subject. Read what you want to read. I just stick with what i know works. I dont hunt with centerfires anymore so i dont bother reading anything about that topic. Ive shot one elk in my life with my brothers .270 and a 140 grain boattail. Thats all the animals ive shot with centerfire. When i go elk hunting i know i'll be using a 348g powerbelt and 100-110 grains RS. I know that will make some serious meat.
