Here is the back story... a reloading friend gave me a bag of at lease 500 148 gn wad cutters. No hollow base just regular flat bottom wad cutters. My friend mentioned that he had these for a long time maybe 2-3 decades. They have a lube ring in the center with a red waxy substance and are very uniform in weight and diameter. I will try to post a picture. I have found some recipes for the HBWC but very few to none for the standard WC. I assume seating depth is pretty much flush with the case mouth, but understand there may be issues with compressed powder with some powders. So questions are is there a significant difference in powder charge for a hollow base and a flat bottom bullet? Should I use roll crimp or taper crimp? How deep should I seat these? Does anyone have experience with a WC Like this or a recipe they would suggest as a starting point?. Powders on hand are 231, longshot, titegroup, clays, HS-6, bullseye, WSF and a few others.
