Explosive Bullets

Heyho,
I started to make a small trickshotting tool in C# for mw3 and noticed when explosive bullets is enabled you automatically dolphin dive after jumping(I used this offset "0x01C29930" from Silent's offset thread, because I was too lazy to search it by my self). This doesen't happen when you just fall off something, only when you jumped before and I saw videos where people used explosive bullets over the dvar(on console) without dolphin diving.
So does someone know if it's possible(and how) to use explosive bullets without dolphin diving on the pc or an alternative(for example changing the bullets to osprey gunner bullets)?

it's on host mode?, i thinks that it's something related with the roll....

Yes it only works when I'm the host and what you mean with roll?

Simple, u need help ?

set the 0xFF to 0x04 u still have the explosive bullets but no dolphin dive
