need help ammos

[rolly]

Need help in understanding shotgun ammos:

What is Shot size?
What is Oz Shot?


How do i know which one would fit best my gun? (benelli m4)

Thanks

The shot size is the number after the #. Roughly translated, a larger number is a smaller shot size. The Oz is the weight of shot in the shell.

A good table is here: http://en.wikipedia.org/wiki/Birdshot#Birdshot
