My brother has a old style Blackhawk that someone modified.
The frame and barrel are .357 but the cylinder chambers have been bored out to .44 mag.
The cases are .44 mag, necked down to .38 with a plastic ring that matches the .44 diameter.
This this shoots with some wallop, but extrememly accurate. I was easily getting two and half inch groups dead on from 15 yards one handed. The gun has pachmyr grips, so it's pretty comfortable to shoot. Of course the gun ends up pretty vertical!
I only have two more boxes of ammo for it, so will want to reload for it.
You can't buy any ammo for this, can you? With a cartridge like this, would I need to resize both the .44 portion of the case and then the .38 portion?
Where would you purchase the plastic ring?
I'ver reloaded lots of straight wall ammo, but not any necked stuff.
Here's the loads I was shooting as he labeled it:
.357/44 Bobcat magnum
140 gr. sierra JHC
22.8 gr H-110
New WW cases OL 1.585"
No idea what velocity these are going out at.
