For great penetration go 158gr or higher. If you are worried that over penetration will happen stay below 158gr and not lower than 125gr. Always use a good hollow point bullet a proven one like Gold Dot, HST etc. If it's self defense. For hunting hard cast WFNGC, or Hornady XTP 180gr work well.I`ve carried a handgun in some form or fashion for a big portion of my life. I`m 65. For much of that time, I`ve carried a Glock handgun. I started out with a cheap Davis .380, then eventually went to a Glock 19 in 9mm, but shortly after, went to the Glock pistol in .45 acp. I know what ammunition I like in .45 loads, I carry Federal Hydra Shok 230 grain. I like the heavier bullet and feel that it makes the better self defense round.
Since just recently having acquired a Colt Python 4" I`ve been looking at the various bullet weights and trying to figure out what is the way to go. An internet search lead me to the Federal Hydra Shok .357 mag load in a 158 grain bullet. I was encouraged in another thread to look at a Buffalo Bore 180 grain round for deer hunting, but if I carry a 158 grain bullet for self defense, the sights wouldn`t be adjusted properly for one or the other. I guess due to that, I won`t consider the Python for deer hunting, only personal protection.
There is a ton of knowledge here, and you guys are very generous in sharing your knowledge and expertise, so I hope to gain from your wisdom. What bullet weight would you recommend for self defense carry in .357 magnum. Am I on the right track with my Hydra Shok 158 grain rounds, or should I rethink that?
I speak from hunting experience only and I always go heavy for hunting and it does an excellent job, and it also on many occasions goes through one side of a deer and out the other.
