I just tried an experiment based on a comment I saw here. Someone commented on another thread that they had used 32 pistol wadcutters in a 30-30. I got to thinking and decided to try something similar.
90 grain 32 caliber Lead SWC (from Hornady, 0.314 diameter) with 4-5 grains of 700X. Tried a ladder of loads and found my 30-30 seemed to like ~4.7 grains.
With 4.7 grains of 700X, boolit seated to the the flat edge of the SWC (just the pointed part outside the case) I got 1277 fps with a SD of only 8.6 fps. Once I zeroed it, It was accurate enough to hit small gongs at 100 yards (small as in 3-4"). This is with open sights on my Win 94-- and for me and my old eyes hitting those small gongs is my standard of excellence.
here's the neat part: (1) low price, $32 for 500, (2) The .314 boolit chambers very nicely, but is so big in diameter that it can be loaded in as-fired cases without resizing! I literally took the fired cases, deprimed, and reloaded without any sizing whatsoever, and got the above results. Apparently, the expansion of my cases when they spring back a little from firing puts the neck at about 0.311, which lets me seat another boolit without resizing. And-- for those wondering, I was loading these in the magazine and had no trouble with the recoil (small anyway) pushing the boolits into the cases.
So, this appears to be a pretty good idea for plinking loads with minimal hard-working of the brass.
