Puru, were you in service? Tommy guns, RPDs, Carl Gustavs............ the .303 LMG would be a Bren or IOF copy with mag on top??
Baljit, good to hear from you again!!
My list:
Disclaimer
In India because of the stupid gun laws, unless & until you are in army/law enforcement any kid from US with little interest in firearms would have shot more types of rifles/handguns then you can dream of in your entire life time..
Diwali cap guns & piston bangers (you pull a handle at the back, insert a patakha in front, squeeze the trigger, a pointy piston hits the patakha and it goes bang, with lotsa smoke and flames emitted from the muzzle!)
Holi water guns shaped like real ones (Skyman, you forgot those

)
0.38 (I assume) revolver
.303 rifle, I assume IOF copy of SMLE
(above two almost 25 years back, one load - 6 & 5 - each)
My old SDB AR in 0.22 and current Precihole Orion in 0.22
Different ARs / APs of IFGians in different meets, including high-end PCPs, sidelevers, underlevers, breakbarrels, etc.
Various Chinese made "airsoft" pistols belonging to my nephews at various points of time.
No more firearms

!!
