Just an expansion and update on my 9/22/20 post. I tried Saeco #315 and Lyman #311466, both sized to .311" and seated to just touch the lands ( Win. Mod. 70, .30-06) without gas checks and was quite happy with the results. Of the two CB.s, #315 was more accurate and I think less likely to lead the bore than -466 (more in a bit). I used my "standard" load of 8.7gr. Unique (thrown) and both Remington and Lake City Match brass neck sized in a Lee collet die and expanded with a Lyman M-die so there'd be no lead shaving of bullet bases. Both CB's were newly cast, but -466 was from the front cavity of the mould whereas I made no attempt to segregate the Saeco 3 cavity's droppings. Primers were Win. LR. Before I forget, I fired 20 #315's and 20 -466's, tumble lubed in Lar's Liquid Xlox.
With respect to bore leading, I got none after 5 foulers and 20 #315's, but by shots 32 and 33, i.e., with -466's I got enough to make me dry patch the bore (those shots are marked on the target below). Fortunately, the leading was easily removed, but returned with the next few shots. Once again, a dry patch removed it and happily, my last five shots were "lead free." Btw, on my Sept. 22 outing I got no bore leading with #-466, but I hand lubed it. Although a bit messy, it is effective and for a small number of CB's, is a lot faster than setting up the lube sizer.
Here's a pic of my targets, with the two 10-shot Saeco #315's on the top and the [10-shot] Lyman #311466's on the bottom. The two bore leading flyers are marked on the bottom right target. Whether #315 would have leaded the bore with more tumble lubing and more shots, I can't say, but for small batch testing, hand lubing works well.
I should add that I fired clockwise so that target #1 is on the left and #4, my last, is below it.
