srsly ram lol
100 pellets.
0.9900990099009901 damage each
I want to do a reasonable amount with reasonable damage.  I'm also going to use a shrapnel model with either 3 or 4 tris an no emitters.  If I do emitters, then no model.  Trying to make it not a LAG cannon, but OP enough because it's a mother loving shrapnel cannon.  But not too OP.  Also recoil that sends you flying with a velocity of 20 TU/sec.
Basically point blank, you're dead, but if you're far away, you'll receive some, but minimal damage.
