Question for the 10ga. Folks

1 1/8 ounce of 7 1/2s doesn't come close to filling the shot cup, and it seems to take closer to 5/8" or even 3/4" of spacing to work.

I have tried putting the fiber cushion in the bottom and the hard spacer on top, and I even tried putting some fiber spacer under the wad.

Does anyone have any tricks to share?

Are you using the x10x gas seal beneath the wad? They are approximately 1/8" thick? It looks like maybe too deep pre crimp by the marks in between the folds and with crimper set a bit too deep will cause the folds to swirl,grabbing too much of the hull to fold in.If on a Mec loader,raise the cam up a little.And with not enough filler this can easily happen.I have also used a 10 gauge hard card beneath the wad instead of the gas seal.It takes up about the same space and does the same job but this test was done with gas seal.One way or another you need a little more filler and adjust your crimper a little higher,or lighter.If you can't get it figured out ill dig out some components tomorrow and see exactly what is needed. The shells I loaded crimped nice.I don't remember if I loaded them on a Mec,or a PW. They both load nice shells.Jeff.

Your goal should be to get your loads to look like the sixth shell from the left.

You need to be sure to have as much filler in the shot cup behind the shot as needed to get the shot column to about 1/4 of an inch below the mouth of the case for a fold crimp. Avoid putting anything over the shot except a very thin over shot card and if you want the best patterns don't put anything over the shot as it will disrupt the pattern even to the point of making a spreader load.

Brand new Cheddite hulls do not crimp as nice as other hulls, especially Federal. The more they are fired the better they get.

If your crimp is normal but has a hole in the center or is swirled and you are loading with a MEC single stage loader you need to adjust the cam.

Looks like I got the loads mixed up that I posted.There is no extra gas seal used in the 1 1/8 oz load which would change the stack height.As other posters have suggested you just need a bit more filler and adjustment to your loader.If using the bp1044 wad in place of the sp10 there may be a little difference in filler needed.I do also use a brass star pre crimper which may help with new hulls.They have sharper corners than the original mec.Looks like you are winning by the last photo.Sorry for any confusion.Jeff

I put an 1/8" washer between the MEC star crimper and the frame of my VersaMec to get a deeper and more defined fold to the crimp.
