Editing .45 Colt (section)

==Uses==
Colt began work on their 1873 Single Action Army Model in 1871. Sample cartridges submitted for Army tests were made by UMC, using the Benet cup primers; commercial ammunition used the Berdan-type primer, followed by the more common Boxer priming. Original UMC loads used a {{convert|40|gr|adj=on}} powder charge and {{convert|255|gr|adj=on}} bullet. This was reduced to {{convert|35|gr|adj=on}} of powder, and later, by the Army, to {{convert|28|gr|adj=on}}.

The .45 Colt cartridge remains in use {{age|1873|1|1}} years after its introduction. It is used as a [[hunting]] load on animals the size of [[deer]] and [[American black bear|black bear]]. Heavier handloads will take the same range of [[game (food)|big game]] animals as the [[.44 Magnum]]. Several two-barrel [[derringer]]s are sold that are chambered in .45 Colt, and some of these derringers can chamber a [[.410 bore]] [[shotgun]] shell without any modifications being required.<ref name=Ahern>{{cite book |last=Ahern |first=Jerry |author-link=Jerry Ahern |date=2010 |title=Gun Digest Buyer's Guide to Concealed-Carry Handguns |publisher=F&W Media |isbn=978-1-4402-1383-0 |pages=207–208}}</ref> Revolvers chambered in .410 shotgun, such as the [[Taurus Judge]] and the [[Smith & Wesson Governor]], are usually chambered for the .45 Colt as well. A popular use for the .45 Colt today is in [[Cowboy Action Shooting]], where the round is often fired from either original or replicas of the 1873 Colt Single-Action Army.<ref name=BBS>{{cite book |last=Taffin |first=John |date=1997 |author-link=John Taffin |title=Big Bore Sixguns |publisher=Krause Publications |isbn=978-0-87341-502-6 |pages=33–37}}</ref>

[[Winchester Repeating Arms Company|Winchester]], [[Marlin Firearms]], [[Henry Repeating Arms]], [[Chiappa Firearms]], [[Taurus (manufacturer)|Rossi]], [[A. Uberti, Srl.|Uberti]], [[Cimarron Firearms]] and other manufacturers produce lever-action rifles chambered in .45 Colt. Colt has resumed production of the Single-Action Army, and many SAA replicas and near-replicas as well as modern-design single-actions by Ruger are chambered for this cartridge.
