Hornady 68gr or Sierra 69gr.
Both are loaded by Black Hills. |

Now, I'm from Utah and don't know crap. So, tell me if I am wrong. But the terminal performance of these rounds is due to the fact that the bullet turns sideways before coming apart at the cannelure.
The Sierra doesn't have the cannelure, so does the increased bullet weight make the difference? |

The cannelure is NOT needed for fragmentation.
There is some evidence that it may HELP fragmentation in some cases, however. The Sierra tends to be more accurate than the Hornady, but the Hornady is a better performer terminally. |

If you're looking for something more lethal than M193, it doesn't exist.

Its the long length and thin jackets not the cannelure.

68gr Hornaday
69gr Sierra MatchKing 75gr Hornaday Some 1:9 rifles work with the 77gr SMK (the bullet used in Mk262 ammo), some don't - 1:9 is just 'on the edge' between too slow & fast enough of a twist for that perticular round.... Faster twists are better though, and the only affect twist has on ballistics is that it limits how heavy of a round you can fire, of course... |

I have heard the 1 in 7 twist is slightly less accurate with 55 grain pills. Is this true? Is there any reason at all not to have a 1 in 7? (I could care less about varmit rounds of 40 grains or less)
