A relative found seven canisters for me and I purchased them all. Now I have access to three more, but seven is enough. If someone lives close to me and wants some I will call and order the other three. I use Trail Boss for subsonic loads in my 223, 6.5 Creedmoor, 308 Winchester, and 300 Win Mag. I also load down my 45/70 to an even 1000 fps with a 300 and 405 gr cast bullet just for fun. It will take me a few weeks to get the other three canisters, but if you want them I will pay for them now. Let me know.
