As you know, your pet load is going to be different than what's stated. The only way to get your pet load is to load it, shoot it and review it.
However, I use the following in a 26" .223 Remington ADL Varmint for p-dogs:
55 gr Hornady VMAX
CCI 400
LC Brass
25.0 gr Benchmark
It produces low ES and cuts holes.
