My fault, should have told you I was building the first one on a Savage 116FSS to make it as easy as possible. If I don't mess with the 300 win shoulder angle I can use 300 go/no go gauges I have access to.Talked to PTG and the reamer is only $138. I'm going to ask for a rough drawing just to check the specs. against mine. I also have access to 2 machinists, 1 which makes the dummys that are used to check the accuracy of mikes,calipers etc. I contacted the premier gunsmith shop is S.C. (in top 10 according to a nat'l magazine [Pop. Mech.,Field&Stream,Sports Afield not sure ,it's on their home page]) top dog out until next week,but was told,and I quote "I don't want to mess with it" I'm going to contact top dog next week because this is contrary to everything I've been told and read about this company. Have a good one paul
