In the errata for dw\row the.damage for.a heavy bolted is changed to 1d10+12. But the errata for row lists the damage for a landspeeder heavy bolted ad 2d10+12. Is that a mistake or we vehicle weapons on row have different damage values?

Pre-Errata: Corebook heavy bolter 2d10+10, RoB Land Speeder heavy bolter 3d10+1. Post-Errata: Corebook 1d10+12, RoB 2d10+10. It looks like a more heavy weapon is installed on Land Speeder.

I agree that vehicular weapons should possibly be more powerful than man or marine portable ones, it made no sense in the war game that a MP lasconnon was no more potent than a landraider mounted one. Still maybe the writers I uld specify that a little.more clearly and say whether or not vehicular weapon ammo was interchangeable with MP ones. Also can a vehicular heavy bolted use special ammo? I'd think so, you'd just need a special magazine and ammo select switch....
