The attached excel file contains tables show pre-calculated additional per ton BV costs for all additional ammo types, simply multiply them by the 'Mechs Offensive Speed Factor and add to the 'Mechs BV
The tables have double top rows, the first shows the specific weapon and the second the per-ton ammo BV for that weapon and double side columns, the left most is the alternate ammo option and the next in is the BV adjustment factor for that ammo types, simply cross reference for given ammo type and weapon
Thunder munitions are on a separate second worksheet due to the fact that they work of off total damage per ton, not BV but the table work the same way
UPDATE: 21 July 2012, 21:09:05 forum time: the orignal had the wrong value for Thunder Augmented multiplication, a new updated version with this fixed should now be attached
UPDATE: 21 July 2012, 21:56:22 forum time: MML-7's and -9's do not get 140 LRM's per ton of ammo, this effects their Thunder ammo BV's
