Okay,
So I spent some time in the past 2 months working on accurizing my New Frontier Cascade Magnum .45 cal. I've had it for 2 years, and just was never happy with the accuracy I was getting. Average 100 yard groups were in the 6" range, although I did shoot some 4" groups along the way. With the help of some wise people from this site

I made some improvements.
First I used a file to remove excess stock material up to the first lug to free-float the barrel.
