Previously I'd been loading my 415 gn "Postell" type cast lead torpedoes in a conventional manner, the load being 57 gn 3f black powder, a veggie fiber wad and the powder compressed a little when seating the bullet in the slightly belled neck which was crimped closed on the bullet. There was about 3/16" jump to the lands. This load mostly did ok on the gongs but success at the 200 yard (paper) "big bull" target consistently eluded me. We shoot 13 shots at this target and count the best 10. My previous best being 9 shots on the paper with 7 in the black so a change was called for. Now I'm using the same powder compressed with a compression die, the same wad, a lube cookie and the same bullet but no longer even neck sizing the case. The bullet is loose fitted by hand and is sitting way out till it touches the lands. The result - 12 out 13 shots in the black with the 13th touching the black and my score jumping a whopping 50%

I'm now only about 6 points off placing in that event. Will try a slightly smaller front sight post next so there's just a little less white paper showing in the aperture around the center bull. There are other benefits from not neck sizing. The brass isn't going to crack from working it back and forth while belling it and crimping it back again, there's no danger of shaving lead from the bullet while seating it (it happens from time to time).
There's still a few of Wile. E Coyote's ideas that I haven't tried yet.
