.12 BB's...for use in grende shells

So I got a big drum of .12 bb's as a gift from an un-informed friend...and I don't want to ask for the reciept to return them...

SOOOOO...can I use them in a 40mm gas grenade without causing any damage? I would assume so, but I want a second opinion.

a lot of people use 12 grams in their grenades because anything else is really a waste. grenades don't fire particularly far. so .12 gram bbs would be great as accuracy isn't necessarily needed and you want it to have as a big of a blast radius as possible. both for 40mm and tornado grenades. it shouldn't damage anything.

My friend uses .12s in his 203 because it allows for longer range, and faster moving BBs. Accuracy is not an issue with them.

.12g are fine, they are not going to cause any damage, like others have said, the 203 is ther to lay down a BB shower, just having a couple hundred BB´s comming at you gives most a moment to pause and rethink what they had planned.

This is all true, and as ADMIN put it a long time ago;
with a 203 you aren't dealing with a long barrel for accuracy, so weight really doesn't make a difference, althought .12s are less expensive and do travel further.
