It has been stated that the boolit core to paper patch should be .001" to .0015" over BORE diameter. What would happen if it were as much as .002" to .0025"? That is still less than groove diameter, the lands should be able to cut through the paper. Would this cause leading? Not leave enough room for paper?
Using a boolit .002" over bore might mean the difference in being able to use the same mold that I already have for lubed boolits rather than having to buy a dedicated mold for paper patching only.
I am obviously new to paper patching. I am having a hard time sizing a .285 boolit down to .278". Lee molds are certainly cheap enough, I have ordered a C277-135RF but if it does indeed cast .277 it will be SMALLER than bore. I assume that wouldn't work because it wouldn't cut the paper into shreds at the muzzle. I am aware this mold could be beagled, but still, that is a lot more work to do.
I have other calibers I will want to paper patch and I am not happy at the prospect of having to buy a new stable of molds. And a lot of beagling to do.
