Am working on some hand loads right now. I use the Win White box for control. For inexpensive (not the cheapest but least expensive), repeatable, accurate and explosive varmint rounds there is no question, go with the Winchester White box. It is hands down an incredible 223 load in my NEF and as Wlscott said in my AR, it is just darn near impossible to beat.
About the Wolf, will it extract from a NEF. I had hell with mine and sent it back to factory, do not EVER want to go there again. Does the lacqure plate out in the chamber?
