Old Gold Cup, new problem

To answer your question on how many 230 gr bullets it takes to weigh the 27 ounces of recommended tension that some suggest, it's 56.347826.

cptmclark,

I do apologize to you as the above information I originally posted is in error.
My math was correct, but I figured it using the Apothecaries' method for weight.

The correct answer is 51.358695 230 gr bullets to equal 27 ounces of tension.
Which is more tension then you will need if the extractor is tuned correctly.

OP please do not be misled by the above (all of the above) the math was incorrect to begin with and so was the explanation and so is problably
everything else in the post.
Now this from Wikipedia,and by the way all unit converters will show Troy and
Apothecary grains to be the same.
The grain was the legal foundation of traditional English weight systems,[3] and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' systems of mass

One grain does equal the same in all three measuring systems, however the difference is in the number of grains in an ounce in the three measures of weight.

Troy and Apothecary has 480 grains in an ounce.

Avoirdupois or what some call commercial weight has 437.5 grains in an ounce.

So yes, along with the information I posted on extractors my math was correct both times.

27 ounces of Troy or Apothecary weight equals 12960 grains.
27 ounces of Avoirdupois weight equals 11812.5 grains.

I did,75 angels fit exactly in the head of a pin.
Nobody uses the apothecary system in the gun industry,for anything.
Only those who wish to confuse or rationalize errors mix systems.
 
It is 76.397865436783 angels

Yes Mr. K but only when you measure the volume by the ancient mesopotamian
system and use the shekel as the unit.The American standard system of weights
and measures precisely indicates 75,that's my conclusion and I'm sticking by it.
Those Gold Cups have a strange trigger group if I may say so.Do you know what that little spring on the sear does?
