Here gust a quick post that I did after reading about an assault cannon vs. a psycannon. As far as they go, odds wise, they are the same expert in one regard, an auto cannon can not get a shaken result vs. Armour 12.
And here my new trick I picked up, that on average .4 penetrating hits each time fired. More on were that number comes from next time.
