I've found that I can easily get 60 grains of 2f Olde E in my modern brass. I did use a compression die, but the compression wasn't severe. I was actually using a 350 grain bullet and was getting over 1,400 f.p.s. out of it. I wasn't too impressed with the accuracy at 260 yards (mostly misses on a 10 inch steel plate), but reviewing the video showed that the shots were actually quite accurate--a spotter (if I'd had one) could have helped me adjust the sights, and I think I'd have rung that steel reliably. As it was, the smoke obscured the target so much, that I had no idea where I was missing. This is an older video I shot with only 720p. You may want to FF through the talking. My son, after viewing some of my youtube vids called me the "Gun Bob Ross".
