I recently went through this after buying a chambered barrel from Krieger. The chamber had zero freebore and a 123 gr scenar was jammed .040 into the lands at an OAL of 2.260. Krieger referred me to JGS who made their reamer and JGS sent me a print of their SAAMI spec reamer. I compared the JGS print against the SAAMI minimum chamber drawing and they were identical. I ended up getting one of these: http://www.midwayusa.com/product/320399/...peed-steel. The chamber came out fine and the barrel shoots great.
Be careful using the term SAAMI spec. SAAMI defines the minimum dimensions. The minimum dimensions may not be the right dimensions for your application.
