Re: 223 coyote loads?? Whats your best load??
I love the hornady 53grn V-max bullets. They claim .290 BC. I load at the top end with Hogdon's CFE and CCI400's, adjusting the load a few tenths depending on the case, and using a longer than standard COL of 2.305". The combo produces 3415fps and 5 shot groups between 1/4" and 1/2" at 110yds every time I shoot it. Just awesome ballistics from a 1:12 twist and std wt bullets.
The first book I ever read was written by Sierra.
