:-) Yeah, I got that. The data I had told me that my starting load was reduced. I just didn't reduce it enough so that I could work up from where I wanted to start. A few tenths less would have gotten me closer to where I wanted to start out.
But small powder spaces, fast powder, and heavy bullets just make absolutely no sense to me. That seems like a pressure spike waiting to happen for the smallest of conditions and I think it's foolhardy. Remember bullet setback when using Bullseye and all of the blown up guns of what was it? 20, 30 years ago? Everyone blamed all sorts of things (detonation is the one theory that I remember best) when all it was was the powder space getting smaller from bullet setback (revolver) and when the fast powder ignited, the pressure spike blew it up. So when I move to a heavier bullet, in this case a very heavy bullet for the cartridge, I'll also move to a slower powder. Not having a pressure barrel I'd rather not guess about what the chamber pressure is but err on the side of safety with slower powder. As I already wrote, I thought I had a reduced load, but my data was meager. Clearly it wasn't a dangerous load, just more velocity than I wanted. I want a target/competition load; I'm not trying for max' energy. Yeah, I just checked and I should be able to safely load more powder, but I don't want to. I'm happy with ejection at this point. The action of the weight of the slide and the spring tell me that I'm pretty close to what I want. But I need more data so I'll put it across the chrono' to see what I actually have. I also need to check for accuracy.
It would be nice to have the data of other folks doing this also, but it's no big deal.
