Reference Collections

Firearms Reference Collection

 
The firearm reference collections at the BCA Laboratories in St. Paul and Bemidji have a variety of pistols, revolvers, rifles and shotguns.  Firearm examiners use reference firearms as samples in function testing to evaluate the condition of similar evidence firearms.  Examiners also use the reference firearms to supply missing or damaged parts to non-functional evidence firearms so they can create test specimens.  The reference firearms also help in serial number restorations.  The firearms show the serial number locations and numbering conventions used by the manufacturers, allowing firearm examiners to identify partially obliterated or restored characters in a firearm’s serial number.  Additionally, firearm examiners will use reference firearms for exemplars in court proceedings, for training exercises and to conduct research experiments.

Ammunition Reference Collection

 
The BCA Laboratories in St. Paul and Bemidji have ammunition reference collections that house a variety of cartridges and shotshells for pistols, revolvers, rifles and shotguns.  The reference collections provide ammunition for firearm examiners to create test specimens similar to the evidence ammunition.  The collection also serves as a Standard Ammunition File for examiners to determine information, such as manufacturer, cartridge type or bullet style, from ammunition components recovered by law enforcement agencies.
