Was wondering if anyone could come up with any tested 1/2 oz tss data for a 410 I have Cheddite hulls and lilgun powder .

Not tested as such but....

BPI in 3 inch quote 14gr of lilgun and 5\8oz  TSS 15 in Cheddites hull for 1215ftsec and 12650psi which is near top end.

11\16 oz 3" lead loads using 13gr lilgun come in at 13,500psi (which is top end) for 1135ftsec

2.5" lead 1\2oz loads using 13gr of lilgun come in at an average of 11500 psi for 1200ftsec

 

13gr would be a safe place to be.

Thanks for that Stonepark would that be the same as TSS 18 but with further ,more or less packing for load  height ?

You will need to adjust slightly more packing than lead (11.3) or Tss (15.0).

If you are using BPI plastic TPS wads, I cut mine down to fit the load and then add a filler wad below to bring height back up.

Thanks for that much appreciated.
