However unless random spread is present I can see both rounds easily conecting during a head on merg.
An AC-10 with one ton of ammo is nearly the same cost as an UAC-5 with one ton. The UAC-5 is lighter, cooler and takes up less crits. We also know that minimum range is going out the window for autocannons. Why should I put an AC-10 in any custom design?
The only way I could see to make both weapons competitive is to play up the jamming risk on the ultras or reduce the firing rate of ultras to match their effective TT damage which would be between the AC-5 and AC-10.
