OK, complicated question:
I have the Lee TL-160-312 mold, and it drops about .312 with my alloy. The mosin I shoot it out of slugs at .312. I would prefer about .313 or .314, but I can get 2MOA out of it with this bullet and 7gr of red dot.
I am thinking about trying to drive this bullet at higher velocities (13 gr red dot or thereabouts). How high can I drive this thing before I'm going to need to gas check it? (in grains of Red Dot, not fps, since I don't have a chrono)
If I do need to size it, Lee only makes sizers in .311 and .314 as best as I can tell. Will the .314 sizer seat the gas checks on the .312 bullets? Will the checks stick out? If so, is that a problem? Which brand of gas checks?
I can afford a Lee sizer, but not an expensive lubri-sizer.
