I Believe I have one, I inherited with my lathe. I don't know the freebore but the guy only used it once and I am positive it was light bullets he used,in tha rifle he chambered. I will let you know just have to go out to the shop, to check.
I have it, its a .250 nk your welcome to see if it will work for you. Was resharpened in 2004 and has not been used since. It is a live pilot reamer by PTG.
My loaded neck dia w/Lapua brass in a bone stock 222
is .248. LDS
Ok, never thought about that. LDSWhen you squeeze down 6br brass it gets a little thicker. I was told that it should come in at around .013 per side after it is necked down.
Thanks,
Tod
