Reloading 28ga. 2 3/4” RST Hulls?
 

For those with experience reloading 28ga. 2 3/4” RST hulls …. I’ve got about 500 of these once-fired hulls on hand and would like to put them to good use. I’ve got Cheddite primers, Universal Clays powder and shot, but am looking for the proper wads for this hull. I know there are published loads utilizing Federal 28S1, Remington PT28 and Gualandi 2838 wads, but I’m not having any luck finding a dealer with these in stock. What wad are you using and an approximate number of reloads you’re getting per hull?

Greg, I just got the Gulandi wads sg28 from BPI. I have some RST 28 hulls also and will use in them with Universal, but I have alot more 20/28. I was hoping to find a load using the Claybuster 28 AAHS wad as it is for straight walled hulls, and I've seen a load with them and Nobelsport, another euro straight walled hull. Maybe I'll call Claybuster.

Claybusters are too loose and you will get powder migration.
Use the SP-28 in 2 3/4" Cheddite Hull, and SP-28II in 2 1/2" Cheddite hulls.
Universal and 20/28 are nearly identical in loading, and You'll be pleasantly surprised what 11grs will do, behind 3/4oz.

Edit: " too loose" in Cheddite hulls. This is the case using fine grain powders like 20/28. Can't say whether it's also true using a bulkier powder.

I’ve got the SG-28 wads ordered. Is a SG-28 wad the same wad as a Gualandi 2838 wad?

Yes.

You can also use the SG-28 in 2 1/2" Hulls for a nice 5/8 oz load

I pretty much make the same shells and I found that some runs of wads will not fill the column as they should and leave a concave crimp with a small hole. I found that a 1/8" 28g nitro card under the BP wad does the trick. Perfect crimps when needed.

Here are a couple of tested loads I've found using 28ga. 2 3/4" RST (Cheddite) hulls. The jury is still out on the quality of these hulls for reloading as I'm finding out that they are not in the same league as the Winchester AA or Remington STS hulls that I've been reloading since the Dark Ages.
