No experts yet!!! Bullet profile on right does not match that of the DM91!
Tau is correct, the bullet on the left is a common mE. I don’t know if it is Czech or German made, or Polish or Austrian!!!
Fede, not surprisingly scored the extra points on the middle bullet. it is a 6.9g Snail. The most commonly encountered Snail is the 2.9g which has an aluminum bullet instead of the brass bullet pictured. See the pictures below. If I understand correctly, the 6.9g load is subsonic!
DK, the Snails come with a lead closed tip and a plastic closed tip. I have seen, or seen photos of both the black 2.9g aluminum bullet and the brass 6.5g bullet with both tip closures. I have only seen the other color aluminum bullets with the plastic tip closure. There also appears to be some difference in the shape of the front flange, but it is hard to tell. The round in the original photo has the tip closure missing. Perhaps an incomplete bullet.
The bullet on the right is tough!
PS: I don’t have either the yellow or green bullet version. There are also red and violet bullet versions which I don’t have. If one of you has dupes in these 4 colors, I’m interested!
