We played this game over at that other board.
When 2d10 rifles have a power level of 3k-4k
and 2d12 50BMG has a power level of 12-13k
what do you give a gun with a 6-7k power.
(or less with this 600NE handguns poor velocity compared to a 600NE rifle)
One easy way to stat it: Half the power of a 50BMG does half the damage: 1d12
Another easy way: If 2d10 is 4k, and 2d12 is 13k, then 6k would be 2d10.7 or so
Again we see the horrid placement of 2d12 for 50BMG messing up reasonable statting. We should have had
2d10 for standard rifles 3k-4k
2d12 for MagnumRifles 4k-9k
2d20(4d8) for 50BMG class personal canons 10k-17k
so we would put a handgun using a magnum rifle caliber at 2d12
and a handgun using 50BMG at 2d20 (or 2d16 for reduced velocity)
But the poor placement/nerf of 50BMG has taken the damage die size that should have gone to MagnumRifles, so guns like 375Mag 416mag 500/600NE cant exist as better than a M1 Garand but not a small cannon like 50BMG.
How to stat it?
How much do we take off a 50BMG to get this gun.
RangeInc: Oh, lets go with HALF a 50bmg (half the power & half the barrel), 60'
Damage: Split the dif between a (7.62)2d10 and a (50BMG)2d12 (2d11 or 1d10+1d12)
Critical: almost as critical as a 50BMG, 20 (or a 12ga... again 20)
Size: you can fire a m16 1handed easier than this 13lb gun: Large (2hand)
