Re: .223 recipes
For the 69 gr matchkings, I found RL-15 worked pretty well around 25gr. But, for PD shooting, I would use a different bullet. I shot the 69 gr matchkings for a while, but heard way too many ricochets with them. You want a bullet that will blow up on any impact. The matchkings also tend to go blasting through PD and keep going. I switched over the the awesome 53 gr V-max, and got better ballistics to boot. The 69 matchking is a great coyote round.
