Rate of fire and length of time firing matters too, even in a .50 cal.

A "cold bore" shot from an average barrel is going to have a different point of impact than a shot from a fouled, hot barrel. As the barrel heats up in an automatic weapon, the point of impact will continue to change.

Hi,

As you said there are large range of factors to take into concideration.

I've been trying to find some data for the exotic .303 rounds but it's a bit hard. You find info about the standard ball ammo. The MkVII (standard infantry round in WWII) and MKVIII (boat tailed round for vickers MG) is about 2440fps and the MkVIIZ comes in at 2550fps but I haven't found anything about the various forms of tracer, incendiary and AP rounds.

Tracers would be interesting as they would change mass as they burnt off their filling.

Cheers!
