At those measurements at the neck & rim they sound pretty much like the brass I ordered earlier from JBA via BACo. I've had no problems with it to date. Don't you go shooting up all your match ammo again Kurt... I went to catch up with you at Baker this year...and all I got was "he shot all his ammo and had nothing left for the match" ! Now we don't want that happening again.
I just went on the TotW website but my search yielded .087 thickness for Shiloh ( & cases marked Shiloh ? ) ...and .090" for Remington ( & cases marked Remington )

May be a typing error.. although my cases have all been JBA marked. May need to give them a call.
thanks again.
