Let me give you a explanation.

Say if some grenade hoarder was sitting near the grenades (depends which type it is) but he doesn't see it and starts to doze off, what if we shoot the grenade, blowing up the guy next to the grenades?

In layman's terms, shoot grenade, it explodes.

that would be a good idea, but cant you do that with fp9a5s? I did that once to a bot. I was using a R9, shot him once, missed him the second but my bullet hit an fp9 and he turned to chunks

I think he means pineapples or some other thrown grenade

I don't think shooting a hand grenade would cause it to detonate.

They are on a 3 second trigger anyway,very little time to react.
Those whom thrown it wouldn't be close enough either(unless they have a death wish,might as well throw the pin instead of the grenade.

Wait, are you talking about grenade pickups, or the actual projectile spawned when you "throw" one?

Both.

say if some guy drops a grenade, right before he runs, you can shoot it, and blow up his feet.

Im pretty sure grenades don't blow up when shot.

I'd like to see bullet physics but into the grenades at least.

I remember an online BW game where I was frantically shooting a grenade to push it away before it exploded. The other players found it funny, but I kinda blew up after that.

I'd be nice if the grenades reacted to bullets like they did in HL2. A simple magnum bullet can act as a quaint return-to-sender stamp.

like they DO in HL2! That franchise aint finished yet!

Uh yes it is... I own it plus episode 1 and 2.Except for episode 3(maybe more after that)I have no idea what your talking about.
I have yet to get deathmatch.(if I ever do)

Volatile ammo pickups (not just grenades) would certainly be cool, and a logical extension of the exploding flamer tank feature and such... Yeah, this definitely needs to be added to BW.

When a grenade is shot, it knocks it backwards. Very useful when going up against bots who spam the T10 grenades.
