I just bought 2500 Cheddite paper 16ga to load for my Heym. I'm using a BP Trim Doctor which works well to get them to 2 1/2". Spinning the hull counterclockwise cuts them off quick and slick.
I have a Precision Reloading roll crimper chucked in my drill press. I bought a BP hull vise to hold the hulls while rolling. I wouldn't buy this vise again since it takes more time to use it as a clamp. I now leave the jaws open and just hold the hull against the stationary jaw with left thumb and index finger which is fast and steady.
The roll crimper makes nice crimps and I have had no problems with it at all. Zip and its done! Perfect every time.
I've loaded a few hundred shells with 3/4oz #8's and they break clays solidly.
I'm pleased with the whole process and results. |

On the hull vise, I adjusted it so it's tight.
It doesn't go over center and lock.
I put the shell in the vise, hold pressure on the lever to keep the hull from spinning. Then just let go of the lever, and put in a new hull.
Fast and easy, with no wear and tear on your finger from holding the hull.
I love those hulls, just wish they were about half the cost. |

I have been loading the same hulls with the same equip. and having good luck.
The question I had concerns wad pressure. I'm using a sg-16 wad, and when used in a plastic hull I can see how much crush I'm getting. With the paper I can't see the only indication I have of pressure is the very slight doming of the over shot card.
I just wanted to get some input from someone that has loaded and tested a bunch before I send in for testing,and my methods are different than what you all are used to.
My next question is if in fact you get less wad pressure from a paper roll crimp, should I up the load I send in for testing a half a grain in comparison to the recipe for a plastic cheddite?

Jack that is a good question. The effects of roll crimp versus folded crimp is all over the place. In some tests the folded crimp have a higher chamber pressure and MV than the roll crimped shells using the same data and components, in others it is just the opposite. If you can swing it I would recommend that you send three test rounds of each with the 1/2 grain difference in powder charge. As far as seating the wad you just need to feel the wad make contact with the powder and let the crimp compress the cushion section of the wad. |

Another way to hold a hull from spinning, is to use a Mec Super Sizer. I have used Super Sizers to roll crimp and skive. Better than any hull of the clamps. They are easy to clamp to any drill press table.
As far as wad pressure goes, there is far too much ado about nothing. Twice Barrel has it right. Let the crimp do the work. |

Thats what I'm using, it's the way to go + resizing is acomplished at the same time; 2 birds with one shot, a true double. No shaving metal with the resizing ring/collar. Also switching between other gauges is a simple matter of changing collets. Very simple. |
