there definately is something off between your readings and the old stuff . If you notice in the 95 data , that even the AA comp shows that much GD , and the Activ G28 is the same wad that is the G wad nowadays . And , it's peculiar that THAT wad would show up in the AA and not the Remmie ! |

I have the WAA16 wads so I think I'll send them in with that load.
I didn't have any data until I got that link.
Thanks

If it were me I'd test my scale before trying again. Check weights or another scale?
If you are loading on a machine instead of individual weighing maybe run through 10 or so and cut apart a couple from the end of the run and see if working the machine is settling your powder drops?
Measure your crimp depth? If you look up Tom Armbrusts article on that you'll see a couple thousand psi increase from excessive crimp depths.
Something has to be off in my mind because your load recipe is light compared to the data. |

I will certainly check the scale, I have check weights. I do have two scales. One digital and one beam. I use the beam for powder, the digital for shot.
Tom asked me not to change the crimp depth. I will measure it though.
I suspect if the published load comes in high, then he will have me adjust the crimp depth.

I agree that something is out of whack here. That Claybuster wad is a loose fit in a Federal hull. |

Jim Can you post/pm what the 20 ga/Gr dot load is that you sent in? Did it use the Ch209 primer like has been talked about on trapshooter?Thanks |

16 gauge Federal Hull NS688 primer. 15/16 oz. #9 Claybuster CB0078-16. 17.5 grains Green Dot.
Velocity Avg. 1261 EV 34-----PSI Average 13420 EV 1000
20 Gauge Remington STS Hull NS688 primer. ¾ oz. #9 Claybuster CB1075-20 wad. 13.5 grains Green Dot.

Makintrax73,
I looked it up.
http://www.armbrust.acf2.org/primersubs.htm
Very enlightening.
An almost 4000 psi difference between .030" and .090".
I measured mine vs. factory.
Factory was .030" Mine were .075".
Maybe we found the answer.
I never really paid much attention to crimp depth, but went by what looked right.
The factory crimps don't look right to me.
I very rarely buy or shoot factory ammo.
I think I learned something very valuable here.

So the only thing pressure testing is telling us is how deep our crimps are? I hope there is more to it than that, and I say this only partly in jest.
A 4000 psi swing swamps just about everything else.

If crimp depth is that important, it should be one of the listed parameters.
Tom said he would test the known published load for free. I may send the same load that was over pressure and pay for it with a proper crimp of .030".
It just can't be the wad. I doubt it is a bad batch of Green Dot although that 20 gauge load I sent in was on the upper edge.
I tested my scales. They look good. The beam scale was right on the money.
I weighed the shot on the beam as well. 410 - 413 grains.

from your data ... it just seems to me the spread on the pressure readings are radical . I would guess that spread might be tighter on a hot load (really good powder burn). Maybe your wads are going to H.. in a handbasket and giving a variance in sealing . |

If you look on the Hodgdon website it list that normal crimp depth should be .050-.055 deep. In my opinion you can do what the factory does. A load that you send off should be within the above or close to it. I do load mine a little deeper. I’m not sure what’s going on but I sent of a green dot load couple months ago and it was 18.0 grains with SG wad and it came back around 10,000 psi, well within the Saami spec. The EV numbers look strange to me. |

I stick to Unique/Universal for 1 oz loads. I realize that's not always an option right now with certain powders being hard to find. |
