Hmm yea I googled m80 fmj ballistic coefficient & got g1 of 393 but g7 was 0.2

You used a ballistic coefficient almost double the real value. USA civilian market develops for anything that has a market. I don't know I like 556 for the weight & range over 762x39. 308 is a hunter or sniper's weapon, not average infantrymen.

Heavy or medium machine gun will be at border post. No need for belt fed squad level Lmg. Also I think Indian Army squad is larger than us army so you will have more lmgs in a squad. Also us army doctrine is everyone but squad Lmg uses semi auto. Indian Army may be different so much extra...

1.) as far as civilian market, think it's better to go for military markets first. Western civilian market has very different conditions & needs. 2.) Insas Lmg doesn't take belt fed ammo, because in most scenarios mmg hmg will not be far. Many countries especially in SE asia will love to have...
