I got a great deal on some Federal goldmaedal Matchking in .308 for my lil brother in 175 grain Sierra hollow point, boat tail. The round is a very accurate and consistent round for factory ammo, my lil brother really wants to try it on deer I say the bullet will explode in the deer as the copper outer is most likely thinner than hunting rounds and not bonded or beefed up on the lower 2/3 of bullet. Yes i told him it will kill the animal but maybe it's not a good choice, any info guys ??
