I am building a 6.5-06 A-Square with 17.5 degree shoulder like an 06, 270, or 25-06.
I had enough trouble buying that reamer and dies.
I have all kinds of 06 and 270 brass that I can neck down. I can't get a 6.5-06 Lee collet neck die, but I can just use a 260 die with a home made spacer.
i have built a couple 260s in the past, but could not get the accuracy or power to keep up with my 7mmRemMags. I am hoping the 6.5-06 can find a niche in my act for at least one of my two tags I drew for 2015.
If not, I will be back with the 7mmRemMag....it is like shooting a deer with a cannon.
