In the past I have relied on RST for most of my vintage shells. Just for ease. I haven’t actually called them, but the site is usually out of everything I use. My stock is about gone….

I reload for Trap at times, I have various powder handbooks, from the manufacturers but, there isn’t anything in that 5k psi range.

What are some good manuals out there that have a good selection of low pressure recipes these days? From Precision Reloading? Or off Amazon? Lyman?

I’m looking for 12ga 2.5” loading data.

Thank you!
