Need a wad suggestion for cheddite hulls(herters) and WSF powder. My reloading manual calls for rem sp16 wads but they are not available.

....and you don't want SP16's for WSF in a Cheddite hull as you will get powder migration... a lot of powder migration.

The best wads are the Gualandi's either the G16 or 16S depending on the payload.

What Mark said . Been using WSF quite a bit lately and it has been a reliable powder . Sp's are REALLY asking for it ! Dr's should be ok as that powder is pretty dense .

Agree with the migration thing. If you can't find data for a better fitting wad and possibly have some WW16 or CB100-16's. Take a close look at published data for both the SP16 and WAA16 in closely matched data. From my research the specs of similar data with only those 2 wads as the main difference the speed and pressure is usually very very close sometimes equal. In my mind, with loads not knocking on the door of SAMMI max spec they are interchangeable.

To the chase... the WAA or CB wads, although not a great fit in Ched style hulls using fine powder, can be flared somewhat to help minimize migration where the SP16 can't. An Over Shot Card under the wad can help as well and may raise pressure a little but less so than a Nitro Card.

Albeit, sending wildcatted loads out for pressure/speed testing is cheap insurance.

All that said (typed) if you just need a couple handfuls of SP16's for the load you're messing with I can help scratch that itch. Send PM if needing some SP16's.

putz,thank you for the offer, am looking to reload cheddite hulls for trap, so I need a bunch of wads. I normally I use the rem game load hull with cb100-16 wads, with the change to the federal type, I want to be ready to sub cheddite hulls for the rem, once my supply is used up.

10-4, being a target load they will be less prone to migration with relatively short life span and not walked over hill and dale. I give the WAA & CB cups a little twist on the edge of the SizeMaster platen before loading.

Wishing CB would put out a CBxxx-16WB (Wide Base) version. Designating it from original narrow versions to meet the needs of folks wanting full length shot protection in a Ched/Fed style/size hull.

Re: post on powder migration
# years ago I was having trouble with powder migration using Longshot in Herters shells with SP16 wads
Someone on the site recommended using plastic discs under the wad
I used a 1.5 inch steel nipple with the edge sharpened on a grinder to punch out a disc using plastic grocery bags
Time consuming but it did solve the migration problem

No published data for 16ga. Some for 12. Some of the other 16 ga shooters at other clubs use it so i tried couple of their loads which I use on the 16 to the 25 yrd. Then on back i use 20/28.
