Got up today made my coffee and went to my reloading room, deleted the spreadsheet I used for the last two days, put the Sinclair and Whidden gauges away. Only using the Hornady Gauges today, using so many gauges got me all screwed up and I kept fighting it.
All you guys that came to help, I really appreciate you jumping into that tornado of confusion I created. What a 2 day ride.
Starting over today, I made 5 separate measurements to get the case base to lands measurement, my CBTO and a COAL for a 90 gr. TNT bullet. Those numbers are; CBTO 1.813" and COAL 2.313".
Then I loaded a dummy round and using Speers data sheet for a 90 gr. TNT with an OAL 2.260" which gave me a ogive number of 1.749".
Subtracting both CBTO's
1.813"
1.749"
.064" jump using a 90 gr. TNT bullet
Is this correct or am I starting another TORNATO?
