I am not well versed in shotgun reloading like metallic, just acquired a 16 ga and some Cheddite hulls- new & primed. From what I glean from the meager info I can find- they are the same as WW hulls for reloading purposes. Are they compression formed 1 piece ? Are they 2 piece with plastic basewad? What WW shell are they the equivalent of for sure? I intend to use moderate to low pressure loads of 1 1/8 ounce and Longshot powder, I have BPI commander wads and Rem SP16 wads.

evidently Cheddite supplies the hulls to Winchester for loading, so Winchester hulls of recent make are Cheddite. They are poly form straight sided hulls- more like Federal or Fiocchi than the previous Winchester CF.

Hi, this might be of help.

https://spreadsheets.google.com/spreadsheet/pub?key=0At1GjTxK0YbudHdQdEUtLWJwbVNyZVNudVF0MGk2WFE&gid=0

Just an absolute wonderful SS that's chuck full of great data. There is a section for Cheddite hulls.

If you look at the SS it tell you that you can use the load data for Win Poly Formed hulls. Lots of loads for Longshot in 1 1/8 payload.

The load that I'm going to use this fall is:

Cheddite Hull
Win 209 primer
21.5 grns 800-X
SP16 wad
1 1/8oz payload
1240fps and 9200psi

Good Luck!!!

Thanks much gjw- that site provided exactly what I was looking for! I intend to develop 2 loads, using #8 & #5 shot, should cover most things.

Apparently either Cheddite or the Asian based companies which manufacture most of these typical generic 16 gauge Cheddite type hulls supply most of the hulls used by the global ammo industry now. If you look carefully at any of the brands which use these types of hulls, you will find they are all closely similar to the point of being interchangeable for reloading any of the recipes which produce mild to mid-range average peak pressures.

The typical modern Cheddite type hull is a polyformed design which has a flat plastic disc with a hole in the middle for the primer inserted into the bottom of the hull base. The biggest variations I've observed are the thicknesses of the various base wad discs and the overall length of the plastic hull tubes used from brand to brand. This is of little importance when it comes to powder ignition, because the actual volume and shape of the combustion chamber is not affected to any significant degree as long as the same wad designs are used in the load. The chamber is always a cylindrical shape w/ a flat bottom, so powder ignition, average peak pressures, and resulting velocities will not be affected to any very significant degree.

The one thing I do not recommend is mixing any of these various Cheddite type hulls together when reloading individual batches of ammo. Keep them separate to avoid crimping problems. The differences in the thickness of the plastic base wads and overall hull lengths will affect the overall shot/wad/column height inside the hull relative to the top of the hull mouth. These differences may or may not produce crimps which are too deep or shallow. However, in many cases, the column height may be safely adjusted by using a wad design with nothing more than a different overall height as long as the wad base is the same. The Remington R16 and SP16 is a good example of this. The Gualandi wads are as well. Filler wads might be used as well as long as they are placed so they cannot affect ignition, the crimps, or the shape of the shot column. The safest, most uniform place is always in the bottom of the shot cup under the shot.

Minor internal and external ballistic variations which could affect overall uniform results can be dealt with easily enough. You can usually observe the results well enough to be able to tweak your powder charges a bit and your reloading procedures accordingly to get good crimps and acceptable performance. As long as you avoid making any changes to any peak pressure recipes, you can usually get acceptable results with your reloads regardless of which of these Cheddite type hulls you use.

"Made In Australia".

AS mention above best not mix different manufacturers to avoid problems.

Working on some reloads for hunting using REm GL (aka SP hulls) and new made Winchester, using Longshot powder.

Just completed shooting some Rem with 20grs of longshot , W209 and SP16 wad, for 1-1/8 oz of #5.

SMOKED the birds at the trap range NICELY, with little recoil.

Should have been about 1200fps with pressure of 8400psi.

Just have work on the Win hull for same.

Hi all, I loaded up some new Cheddite hulls yesterday using the following recipe:

Cheddite Hull
Win 209 primer
21.5 grns 800-X
SP16 wad
1 1/8oz payload
1240fps and 9200psi

They turned out very nice IMO. The Green hulls are #5 shot and the Red #6.

No problems with the crimps and easy to load. Here they are:

Good Luck!

The current Herter's shells from Cabela's use Cheddite hulls. The box says they are made in Italy.

Now thats what I call a global economy.

Anyone have any loose primer issues? On the ballistic products website they have a note saying that primer pockets are .001" larger than standard. Anyone loader win209 primers in these hulls?

Federal 209A and Winchester 209, both fit tight without resetting the primer pocket in the green 16 gauge Cheddite hulls.

off topic a little , but American primers fit VERY loose in the Rio 16s I've tried , every one has needed the pocket resized
