Dave,

When I cleaned out Papa's house I found about 300 or so once fired empties he had been hoarding. You can still get WW Xpert 1 oz 2 1/2 dram loads at 1165 fps. A great load and expensive, but is a way to get empties.

Thanks Harry. I wonder with the Winchester being a straight walled hull if a Cheddite hull has about the same capacity.

Dave, Here's what I've been useing in my 16ga DH.
Cheddite Hull
Win 209
DR16 wad
16.3 gr Clays International
7/8 oz #8 lead
1175 fps 6700 psi

Nice load thats murder on clay targets.

Thanks Robert, Looking at Harry's and your load they seem very close. I think I will order some Down Range wads and some Cheddite hulls and give it a go. Thanks again!

I ordered some Cheddite hulls from Precision Reloading. They come primed with Cheddite primers. Does anyone know how significant the difference is between the Cheddite and Win 209? I am wondering if I can use this same load for the first round, then I will be using Winchester primers after that.

I just realized that I already asked that a few days ago. Maybe no one knows. I will see what I can find.

And to finish this one sided conversation, information on the low pressure group site says that win 209 and Cheddite 209 can be substituted for one another.

[Autumn Daze]

John, That is true. Pressures realized with both the Cheddite and Winchester primers are very similar.

Is this Cheddite hulls 2-3/4" or 2-1/2"
Graff's is no longer carrying the SG-16 wad.
I have about 10,000 on hand, but will have to find something different some day.
Thanks, Dave

John C, I have done exactly that, loaded the new preprimed hull,then after first firing reloaded with Win 209's. Like Dave said performance between Win and Cheddite primers is very close.
