Looking at these loads I can't seem to find which one is accurate in searching the forum and why there is a difference with the RST hull. Anyone shoot any of these? I'm looking for a new load when my 7625 powder runs out.

Yes, if somebody can chime in on this it would be greatly appreciated! I have been shooting the first listed formula with very good success on grouse and woodcock. However, I was using it the RST Cheddite hulls! I didn't realize there was a distinguished difference between cheddite and RST cheddite? Please advise! |

From what I can find looking into the subject there is no difference in hulls. So if that is the case what is the reason for such a difference in grains/fps/pressure? Which recipe is most accurate? |

There is absolutely no way of knowing which one is correct.......they all could be.
I would use the Hodgdon data. |

I have always heard that BP data is a bit suspect. I go with the powder manufacture, Lyman, of something that's been tested by Tom.

I have been loading cheddite hulls 23/4 not 21/2 for sometime here are my loads that I have tested and shoot allot hunting and skeet.
Herters hull(cheddite)
20.9 Universal powder
Downrange wad DR-16
7/8 once of 8 shot
Fiocchi primer 209
Crono avg 5 shots=1140fps
Herters hull(cheddite)
21.9 Universal powder
SG-16 wad
1 once of 8 shot
Fiocchi primer 209
Crono avg 5 shots=1291fps
Hope this info helps
These loads crimp perfectly |

The one loaded in the RST hull is one that is sent in for testing by one of the 16ga members , doesn't say who and we don't have the spec sheet on it . Maybe the crimps were deeper than the loads tested by Hodgden .
The Ched hulls that I have are no different than the Rst hulls I have so I don't think its the hull |

Also reloads through once fired hulls often have an increase in pressure due to increase friction of the wad against a roughened hull wall. The data from Hodgden was very likely new hulls and the RSTs were likely at least once fired hulls.

So maybe the effect is not as profound on light loads as I had thought but the hulls tested were some of the best every made so it would be interesting to reproduce with the cheddite hull. |
