.25-45 sharps

What does the 45 stand for ? Thank you Joe

I could be mistaken, but I believe it was for the amount of black powder used. 45 grains of black powder.

The 25-45 Sharps I know about is based on the .223 Rem.

The "45" is about length of the case in mm.

Here is a link to their web site: http://store.srcarms.com/default.asp

The 45 does seem to be 45 mm for the case length as JASmith mentioned. I looked up a couple of articles via a google search and looks to be an interesting cartridge. Maybe someday I may look at it a bit closer.

Thank you fellas, I thought the same thing in regards to the length, just need reassurance that they mixed imperial and metric together

Now, way back when, when smokeless powder was in its infancy, blackpowder nomenclature was still used, .45-70 was .45 caliber with 70 grs of blackpowder.

When the .30-40 Krag came around, people started to wildcat the case up and down in different calibers. One such wildcat was the .25 Krag. If I'm not mistaken, I think the .25 Krag was the basis of the .25-45 you're talking about.

Usually, the .25 is the caliber, and the 45 is the amount of powder it holds, 45 grs.

No, as noted above the .25-45 Sharps is basically a necked up .223 to take a .25-caliber bullet. It was designed specifically for use in the MSR/AR-15 platform about 3-4 years ago.

That's going to confuse a lot of people!
It should be .25x45mm

My bad here. I saw the name Sharps and immediately thought old I should have researched this before I answered.
Look before you leap!
