The screened stuff was really firm but much larger granules. I may experiment with polishing them in the tumbler with a little powdered graphite.
I only got to shoot one round ball before the snow storm pushed me out. I used 80gr of screened and a 177gr ball, speed was 1293fps.
I was considering investing in a larger 20tn H-frame press but screened is working so well I don't think there's a need to invest more in pressing.
