Triple Se7en& UC

I grasp the picture, but it just seems odd to me that a major manufacturer would have that kind of tolerance... as an example and an example only, I have two Remington's a 24" and a 26" my nephew has a 26" - these guns are years apart from each other but they virtually have the same bore diameter, notice I did not say exact. I have 4 Green Mountain 1/28 twist barrels, forgot to say Hawkin barrels,- 3 regular steel and 1 stainless purchased over several years - they are virtually the same and finally the 2 A&H's from different generations one from Weston - one from Provo and again virtually the same extruded bore. In fact all of these 50 cal bores use the same sabot and the same bullets with out a problem...it mystifies me....

This is why I have problems in my mind about these TC bores... I prayed when i got mine i the correct bore and it worked out so I am happy. Mine is a stainless is the variety occuring from Stainless to Z5 models? Got to be a reason - I know you already told me....but darn, not a good way to run a business.
