Hey Michael, it was good to see you again the other day, too many years between visits. I took your advice and have the parts to put a 10.5" 300BA on the way. When I get it together I'll get up with you and pick your brain on a load for it.
Link please, gOOgleFu got me furniture.A great source of brass at reasonable prices is Evergreen.......... I bought 4000 pieces recently........
Was it Everglades Ammo instead of Evergreen?
