62gr & 75gr Speer Gold Dot is my choice for defense ammo in my ARs.
Johnny's Reloading Bench has a great YouTube video on them with ballistics tests. Sorry but I'm not sure how to embed a YouTube vids on this forum. https://youtu.be/LZevnNZwseM Last edited by Tig-it; December 5, 2018 at 07:06 PM. |

Just for fun, I'll post a link to a youtube video of a guy named Paul Harrell's video on the differences between 55 grn ball, and 62 grn penetrator rounds.
Mr. Harrell always puts out good videos pertaining to shooting.  https://youtu.be/bKQizbg1zBw |

Maybe not quite the same thing, but I have a recorded load of 62gr FMJ-BT with 24.5 grains H-335 that chronoed 2724 out of my BREN 805...if that helps at all.
