You need to know the make and model. If you can post THAT here, along with a serial number, we may be able to date your gun.

What if you have the mean and then 2 more numbers how do you find the new mean?
You can only answer this question if you know how many numbers there were before. (If you know how many were there after, then subtracting two gives you the number before). So suppose there were n numbers with mean x. And you add two more numbers, a and b. That means the sum of the n numbers was n*x. Sum of the n+2 numbers is n*x + a + b So the new mean is (n*x + a + b)/(n + 2)
How do you find a geometric mean?
If there are only k numbers x(1),x(2)....,x(k), the geometric mean is the kth root of the product of these k numbers. Example: find the geometric mean of 4,3,7,8 We want the fourth root of 4 x 3 x 7 x 8 = 672 =(672)^(1/4) = 5.09146 is the geometric mean. The geometric mean is normally defined only for a set of positive numbers.

You cannot. Suppose the mean of a set of numbers is m. Now add the pair of numbers m-x and m+x to the set, where x is any number. The new, extended set will have the same mean as before but two more members.
