square deal b
In recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. The order of the magic square is the number of integers along one side (n), and the constant sum is called the magic constant. If the array includes just the positive integers

, the magic square is said to be normal. Some authors take magic square to mean normal magic square.Magic squares that include repeated entries do not fall under this definition and are referred to as trivial. Some well-known examples, including the Sagrada Família magic square and the Parker square are trivial in this sense. When all the rows and columns but not both diagonals sum to the magic constant we have semimagic squares (sometimes called orthomagic squares).
The mathematical study of magic squares typically deals with their construction, classification, and enumeration. Although completely general methods for producing all the magic squares of all orders do not exist, historically three general techniques have been discovered: by bordering method, by making composite magic squares, and by adding two preliminary squares. There are also more specific strategies like the continuous enumeration method that reproduces specific patterns. Magic squares are generally classified according to their order n as: odd if n is odd, evenly even (also referred to as "doubly even") if n is a multiple of 4, oddly even (also known as "singly even") if n is any other even number. This classification is based on different techniques required to construct odd, evenly even, and oddly even squares. Beside this, depending on further properties, magic squares are also classified as associative magic squares, pandiagonal magic squares, most-perfect magic squares, and so on. More challengingly, attempts have also been made to classify all the magic squares of a given order as transformations of a smaller set of squares. Except for n ≤ 5, the enumeration of higher order magic squares is still an open challenge. The enumeration of most-perfect magic squares of any order was only accomplished in the late 20th century.
Magic squares have a long history, dating back to at least 190 BCE in China. At various times they have acquired occult or mythical significance, and have appeared as symbols in works of art. In modern times they have been generalized a number of ways, including using extra or different constraints, multiplying instead of adding cells, using alternate shapes or more than two dimensions, and replacing numbers with shapes and addition with geometric operations.
Dillon Square Deal B set up in 45 ACP. Works great, I’ve loaded at least 1,000, maybe 1,500 rounds on this since I acquired it used a few years ago. Prefer to meet in Tigard/Tualatin area.
Similar to the other ad I have, I bought this years ago and haven't even set it up.
This one is not rebuilt, but looks in good shape.
I can meet around town and down to Albany.

Well, I bought this 14 years ago and had Dillon service it, but it has sat in the box, unused since I got it back from Dillon; so I guess I'm not going to use it.
I just opened the box to take this picture. The rebuilt receipt is in the box.
The machines are over $600 new and the conversion kits...

Picked this up from a friend today and I don’t have the time or patience for it. Appears to be in pretty good shape. Handle cranks. Little bits of rust on some screws I tried to capture in the pictures. I don’t know a ton about it. It appears to be set up for 9mm but it looks like it all comes...
