257 roberts reamer lead ?
What is the length of free bore prior to the lead on your 257 roberts chamber?? I'm in the process of building one and am wanting to know what others have used and compare it to my approach. Thanks

I don't know about others, but I use a separate throat reamer which cuts a throat .0005 over bullet and has a 1.5 degree leade.
