AT 75mm core diameter?

[llobdelljr]

What is the core diameter of AT 75mm reloads? Is it the same size for different sizes and propellant formulations? Thanks!!

My guess is going to be it varies by propellant type and motor length.. For 75mm .875 - 1.125" ?

some long motors have larger cores near the nozzle.

The core sizes on specific motor are on the instruction sheets on AT's website. A few are on their assembly dwgs.
