That is good work.

I have had two of the Win 670, both in '06. And they both shot just like that with just about any 165, and also Hornady 190 btsp. And yes they shot even better after tweaking the trigger and bedding the action with Acra-glas in a manner to float the barrel.

And yes, when I bought a Chrony, they were over 200 fps slower than I had thought. But the groups were still tight.

People who choose to brew up their own storms bitch loudest about the rain.
