I was wondering when someone would mention 22lr. As a kid and a young man it was always the smell of having fun with my friends while we went through a brickThe sweet smell of Eley .22LR match ammo on a weekend morning. When you cycle the bolt, you can see the faint remnants of smoke exiting the breech, then it hits your nose.
The next best thing is Hoppe's numba 9 because it reminds me of my first and favorite mom&pop gun shop where I bought my first rifle circa 1989. It was a Ruger Varmint Tang Safety M77 in .308 topped with a Leupold fixed M8 8X. When you opened the door, you entered another world. It's long gone now...
Peters blue paper shot shells had that type of odor.Red Dot powder and paper hulls! now that smell is like no other.
Yup, but it's the first thing I put down my bore after a match, followed by Butches......Five or ten shooters shooting three grains of Bullseye & whatever that smoky wax bullet lube was on 38 Special wadcutters on the basement range of the local police dept. with no exhaust fans every Friday night.
Haven't smelled any Hoppe's for years, but remember the change from the original formula smelled different enough to notice.
