where can i send a shotshell in for psi testing? that would be very handy. as i have deviated a lot from published data, hell from old reloading books to new ones I've
seen some pretty drastic charge swings.

There are others, but these are the ones I have worked with and can vouch for their accuracy.
Tom Armbrust, is the most experienced of all with shotshells. So if the loads you send in for testing aren't working out, Tom will be able to give you the proper advice.
Some tips for getting good data.
Crimps MUST be well formed, between 3/64" and 1/16" deep and consistent for each load. Half a$$ crimps will have the technician doubting the loads before the breech is closed on the first round.
Hand weigh all powder and shot payloads.
Send clearly written component information about the loads you are sending. If you can find the Lot Numbers for the primers and powder, include them with the load information.
Send at least 5 rounds of each load that you want tested. Sending an extra round so that the technician can verify the components, if there is a question isn't a bad idea.
The load must fit properly in the hull, if it doesn't, you need to rethink the load.
Testing isn't inexpensive, so use common sense when developing new loads. Choose wads(correct diameters and length) that are made for the hulls you have chosen. Choose powders that are correct for the shot payload. Choose components, that you can get on a consistent basis.
Talk to the company before sending any loads to them, they might be able to steer you away from sending a load that has no chance of working.
I hope this helps.
