My venture into casting Boolits began with a Lee 2cavity 356-102-R1 and plain old COWW's. These are dropping right around the 104.5gr mark +/- .6gr and the diameter seems to be steady at round .3575 to.358.
When I first started loading these I was getting a small lead shaving at the mouth of the case and when I pulled one apart I could see it went the entire circumference of the bullet and all the way down to the base. So at this point I still do not know if it was all shavings or also some swaging as these first tries were not sized but I get a feeling it was some of both. I do have a topic here on the forum about this.
Before I shot any I was able to get a Lee pass thru Sizer to size these to .356" which is what the samples I tried were and those shot very well. After sizing the next batch and then re-tumble lubing them I didn't see any signs of shaving. So I loaded up about 40 of these using AA#2 @ 2.8gr.
Range report; not so hot. I think it was partly because I haven't been feeling well the past week and after I started shooting I got tired quickly and was also having a hard time focusing and seeing the sights. But they all went boom and they all hit within a 6" circle at 10 yards. Also this was at our old indoor range and the lighting is not the best. I also noticed that these seemed to be a bit more smoky then the previous loads I shot but then those were also outside.
Shot these from 2 different guns. A Witness Pavona and a S&W EZ. The witness ate them all up while the EZ had some failure to feed and failure to fully chamber. Was also stove piping the last round in the EZ and that happened with both mags. We seen this with factory loads as well when we first received the gun and then with my reloads it seemed to go away.
Now I may try to load up a few more and load them down to 2.6" and see what happens.
