If you use gun club data with those hulls all of your lead will fall out. Deep crimps. Those hulls can hold alot of volume. Look closer to Fiocchi and cheddite data. Use Cheddite primers and they will fit with no problem. The rios are a straight walled hull and use the Federal wad or a knock of (Down Range or Claybuster). The cheddite data, which is what most of the euro trash hulls are, is 19.5 gr of Red Dot with the Fed 12S3 wad (or knock off). The CB's or DR's will save you about 40-50 dollars a case. This info is available on Alliants website. If you have the chance and are at a range, pick up any Remington hull, they will last longer and reload better than the euro trash that you have now. Less voluminous meaning less powder. Although 2 grains is hardly saving that much in the short run, over a pound of powder, the difference between 17.5 and 19 grains is enough powder for 41 extra rounds. If you are just loading for trap look to some of the 1 ounce lor 7/8th ounce loads. There will be the real cost savings and shoulder savings.
Also, those stars on the bottom mean they are a cheddite hull
