Have to agree with all the advice on the .223. I use a Rem 700 sendero in .223 as my main rifle, but if you want to see the red mist try the 25-06 with the 87gr Speer TNT. Do not use this load for any fur bearer if you plan on selling the hide, there aint enough sewing thread in the world. I always take the 25-06 along for when the wind comes up or I start taking the long shots so I loaded up the 87gr TNT but wind drift was still bad and I went back to the 100gr ballistic tip.
