I've seen them online up to 165rd. and all within 10-15.00 of each other.
I think I'll carry two rounds. The M-79 I have is not my primary weapon, and I can't see having that many opponents in one spot to use it much. Maybe some really big outdoor game..
I figure it'll get used as a room clearing tool mostly.
I'm in the process of getting a claymore command-detonated mine, which would make for a good running ambush tool.
Thanks for the advice,
Chip
