I apparently have a wide selection of ammo with no guns for said ammo (includes 30.06, 9mm Luger, a metric ton of 22 long rifle bird shot), a Walther magazine (again, no gun for the mag), some weird 357 rounds with flat tips (like completely flat), some rounds that looks like the bullets are coated in a really hard plastic or ceramic (wtf?) and somehow have M1 blanks (says so right on the box). And brass. A lot of empty brass.
Or maybe it might be easier if I post pics here and you knowledgeable people could comment?
Thgere's just too many firearms that use ammunition for there to be a web site that will tell you what gun you should have for which round of ammo.
Examples ... .30-06 ... there's dozen and dozens of rifles chambered for this round of ammo. The same is true for 9 mm Luger, which also goes by the names 9 mm Parabellum and 9x19 mm. Hundreds of different handguns and even a few rifles chamber for it.
The .357 Mag flat nosed ammo are generally known as wadcutters. It's identical to any .357 magnum round with a bullet designed mostly for target shooting.
M1 blanks are likely either .30-06 or .30 Carbine rounds, but may be an entirely different cartridge, this is a guess) used for training or in some cases by the military for launching rifle grenades. It's just made to make a noise and cycle the action. They're crimped at the end rather than having a bullet. All this is assuming that they are either of the previously stated cartridges ... do they say what caliber they are?
Hard plastic, ceramic bullets are a relatively new thing and are designed to prevent barrel wear. Do a google search using the term 'ceramic bullets' and you'll find both pics and info on this. Like I said, it's a newer concept, so there's plenty of info out there on them.
As for the .22 bird shot. It is what it say's. .22 caliber ammo for use in a .22 rifle/pistol chambered for .22 Long Rifle. Rather than a bullet, the end is crimped and the shell contains small pellets for firing at small game. It's not a very effective round of ammo for such things, but does work. Basically a shotgun type shell created for 22's.
As for one site though ... there really isn't one that will tell you what gun goes with what round ... as there are just too many firearms that are chambered in the same calibers.
