Terry;
I'm not a roll crimper but find it a very satisfying to look at. For clarification, which roll crimping tool in your first picture is the preferred one and what is meant by the "pin" in the crimper? Maybe if I live as long as you I'll take up roll crimping when I have some free time. |
It holds 5c collets. It doesn’t rotate but threads down and locks the collets in place. I have one for hex as well. The machinist at work showed me today we have a hardinge indexer for 5c as well.

I just went to the " reloaders network " web site and couldn't find the roll crimpers. Any help ?
|
On the main page, click ‘Store’, then Shotgun, then the gauge you’re interested in.

Jay,
I have a 16 gauge precision reloading roll crimper and it works great. |
Thanks, I found it. Their crimps are a whole lot deeper than mine. I think pressures may raise with a crimp that deep. I could be wrong - maybe someone else can chime in.

The top of the shot only needs to be about 1/8" below the rim of the hull, and the rollover will be 180 degree reversed. With regard to pressure, there's lots of data out there. All I have sent to Precision have been lower than folded samples of like charges. The four shells, below, are, left-right: Factory Eley 2.5" 5/8oz. Once fired Winchester paper Super-X hull, trimmed to 2.4", Fiocchi RO28 wad, 5/8oz. New Cheddite hull, trimmed to 2.5", Fiocchi RO28 wad, 3/4oz New Cheddite hull, trimmed to 2.5", BPI SP28 wad, 5/8 oz The difference between the Cheddite 5/8oz load, and Winchester Paper 5/8oz load is because the Paper hulls had very high base wad. The Winchester Hull with the SP28 wad only allows 9/16oz when trimmed the same. |
good looking roll crimps to me wish mine looked that good....charlie
