I have a Bushy 20", my friend that I shoot with regularly has a 16". We both get around 2"+ with Wolf. With reloads, his shoots in the <1" range while mine is more in the 1-1.25" range. With cheap Remington,they are both slightly better than the Wolf. I have been wanting to get ahold of some Winchester white box, but it is always sold out everywhere I go. These are both scoped BTW so with an red dot, I think you are doing pretty good.

When the shooting gets serious, I get out the 24" SS Varmint flat top and shoot in the .5" range.
