SL 900 Crimp issues

Have or had everything adjusted-I thought

Running into issues with the final crimp

I'm using STS hulls  with 1 1/8 shot charge

when I crimp- it is finishing way back in the case leaving a hole the shot can pour through- is this normal for this shell

If not how do I adjust it where it crimps correctly

any help would be appreciated

STS hulls tend to be irregular in length. Use calipers, find the longest fired hulls, use those to adjust both the start and final crimp. A hole in the center after final crimp indicates the start crimp needs to go down an additional 1/4 turn or so.

Thanks

a little more then a 1/4 turn and they closed like new

Appreciate the Dillon help
