Civil war sniper round [add pics]

tx gun runner · 07-09-2009, 01:21 PM

The 40-60 Maynard is one of the oldest cartridge , designed for a civil war sniper rifle . The barrel on a Maynard interchange like the Thomson Contender . It still is use in a lot long range buffalo matches today . The original round was a flat washer solder to a tube . There was a fat head and thin head and then Sharps made a 40-60 straight wall and today it can be made using 30-40 Krag brass . So I decided put that round into a High Wall for a target gun .

To make the brass for 40 Krag , 40-60 Maynard or 40-60 Sharps straight
which are the all the same with different names

So you buy brass for 30/40 and then how do you reshape it? Resizing die?

Fireformed. That's what the Unique and cream of wheat filler are about.

Gunrunner, Do you seal the front of the case with a card wad or wax? Or just keep it pointed up?

I've never heard of that.

That is the standard way of making "improved" cases where there is less taper and a sharper shoulder to increase space. You fire it in the opened chamber and the pressure forms it to the larger cavity. In this case the bullet is too small for the bore so a filler is better. You then resize the case with the new dies and reload it.

Well I learned something new.

Wildcatters get a bang out of it.

Oh that was so bad, Mac.

Mac ....... I use a spit ball most of the time to hold the filler in .. I had a original Maynard like in the paste and was a super shooter with a short light bullet like the muzzle loader bullet , it all most had a round ball twist . The Maynard rifle is to light for 400 gr , unless you are into pain . That's why I built the High Wall with a heavy barrel . I built that gun out of parts laying my buddy's shop . That a Douglas barrel which is the only thing paid for . Everything else was free , the sight are off my 22 ballard , and the chamber is lathe cut , not reamed . And bullet mold is lathe cut also using a old 30 cal mold .
