I've loaded a bunch of 20 ga tss but lost my load data for 410 tss loads I got from Hal. I'll be using mp300 powder and a 7/8 load if anyone has any data they can share I appreciate your help.
I’m also interested in a 410 TSS recipe. I bought a MEC 600jr 410 loader at an estate sale a few years ago on the cheap, because it was missing a couple parts. I finally decided to order the parts and am up and running.
Brian Sent you a text message, but no response. If you don’t have my number or your same number still, pm me. There’s some guys on the forums that have good 410 recipe with that powder. I think on here has a good one. I’ll send you their contact.
