[QUOTE="DBoone, post: 1679677, member: 104920"] Thanks, looking like I have a .180"ish freebore to me. When I inquired with Proof they told me they only do SAAMI spec chambers. I agree there is room for error in tools and people using them. I'd be ok with +/- 0.010" between numbers with that in mind. My concern and why I'm not seeing the 0.050" difference between reamers. If I work Rhett's numbers (135 Berger @ 2.315" with a .155" freebore) compared to mine (135 Berger @ 2.340") it still puts me around that .180" freebore range. [/QUOTE]
