I'd like some advise on bullet grain. I purchase bulk 9mm ammo on the regular and have pretty much always been buying Federal 147gr. I've shot Federal for years and its reliable, accurate, and reasonably priced. What are the advantages/disadvantages to buying 115gr or 124gr vs the 147gr. I know that the 115gr has the most velocity but may not penetrate as well. 147gr has the weight to really penetrate but the velocity in most cases is sub 1000ft/sec. 124gr seems to meet in the middle. My question, which is best for stockpiling for when zombie times come? The difference in cost between the three is negligible to me, I'd just like to know the pros/cons of each, and what you all wound consider to be the best choice. Thanks.
