can shotguns like a mossberg 500a shells can be traced by police?

Question

i never did a crime that i never had to do

Answer 1

Old fuzz is right.
It is called toolmark identification.
Anytime a piece of metal hits something it leave microscopic marks that can usually be matched. That is if you get the specific weapon. A shotgun like the Mossberg, uses a striking pin (firing pin) to hit a primer on the shell. The striker hits in a certain way and can have defects in it that leave a specific mark on the shell primer. When you pump the 500 the extractor "grabs" the shell. This metal to metal contact leaves an even better set of toolmarks to compare.
Someone else said all handguns have grooved barrels. That is the law and it makes the bullet travel better but it is not true. Smooth bore barrels are made all the time by amateur gunsmiths. The guns are not accurate but it makes bullet comparison a lot harder.
In the old days we had and "open case" which actually housed expended rounds from unsolved homicides. Whenever a gun was seized on the street it was test fired and an examiner would try to remember what was in the open case and compare it.
Now we have a couple of data bases and all bullet evidence is digitized and placed into the system for comparisons.

Answer 2

GOOD QUESTION:
ALL SHOTGUNS HAVE A SMOOTH BARREL-
ALL PISTOLS AND RIFLES HAVE A NURELLED GROVE FOR VELOCITY FROM THE BARREL WHEN FIRED
A 500 a SHELL CAN BE TRACED TO THE MARKET IF YOU LEFT THE SHELL BEHIND
THE RIFLE OR PISTOL LEAVES A GROOVED MARKING ON THE BULLET AS WELL AS THE CARTRIDGE
THE CARTRIDGE OF THE SHOT GUN SHELL CAN BE MATCHED TO THE FIRING PIN OF THE WEAPON AND THE ANGLE IT STRIKES THE SHELL.
BALLISTICS AND SOPHISTICATED ANALYSIS COULD MATCH BOTH AND TIE IT TO THE CRIME
THE EASY PART IS WHERE THE MOSSBERG 500 A SHELL WAS PURCHASED WITHIN THE AREA OF THE CRIME--IF THIS WAS AN OUT OF STATE HIT THEN HARDER TO FIND-ALSO DEPENDS UPON THE INVESTIGATOR.

KEY FOR THE CASE IS A SHELL LEFT BEHIND COULD POSSIBLY GIVE A FINGERPRINT ON THE CASE AS THE SHELL HAS TO BE LAODED TO THE BREECH FOR A SHOTGUN AND THE THUMB AND FOREFINGERS ARE USED FOR THAT
-IF THIS IS FOUND THEN I WOULD TRACE THE FINGERPRINT, THE WEAPON, THE SHELL, THE PURCHASE PLACE, PURCHASER AND THEN PIECE IT ALL TOGETHER AND THAT IS THE FUN PART TRYING TO PUT THE PUZZEL TOGETHER.

Answer 3

No, shotgun shells cannot be traced, like a handgun. A shell can be traced to a specific type of shotgun, meaning the gauge can be determined, but it cannot be traced to an exact shotgun. It has to do with the way the barrels are made.

Answer 4

Yes and no. Can the "CSI" look at a expended shotgun shell and tell if it was fired by a Mossberg shotgun. No. Can they match the expended shell to a specific shotgun by matching the breech face and firing pin marks. Yes.

Answer 5

Only if you leave empty hulls at the crime scene.

Answer 6

yes each gun has a distinct signature to it...Period

Answer 7

you're such a phony loser lol
