AMP Aneal codes. Pilot. 73
Mk 1 STD mode use code 82
Aztec mode use 142 for Hornady, 141 for Alpha.
If you are going to analyze using Aztec use pilot code 073 C
These are COAL to the lands for various bullets. These were measured on brand new barrels with the OG reamer and the Current, JGS and PTG. there was a +/- variation of .005 either side, so reamers as well as bullets vary lot to lot. They will always vary a tad Chamber to chamber , Rifle to Rifle. . Back off .010 as a MIn.
103 Vapor Trail 2.560
105 Berger Hyb 2.585
105 JLK 2.590
108 Hornady ELD 2.545
110 H A Tip. 2.620
112 Barnes 2.605
115 Nosler RDF 2.545
115 DTAC. 2.580
In looking at these #'s the current .120 FB is still the best for the standard Reamer as it will work well for everything and is the best for 105-109 Berger Hybrids, 112 Barnes and the Hornady 110 Atip
If guys were wanting a specific chamber cut for 115 RDF, 115 Sierra, 108 Hornady ELD or 103 Vapor Trail a .170 FB would probably be ideal for those 3 bullets which GAP does have a .170 FB Reamer but Its only used on request.
