HELP!
I've look all over for information on this, and just can't find any - which may mean that I'm overthinking this whole thing.
I cast up a pile of 185gr boolits for my Enfield using the Lee c312-185 mold. There is a cannaluer on the boolit that when slipped into the cartridge gives me a C.O.L. of 2.796. I cannot find any reloading data on this anywhere - the books, my app, the internet - nothing. So I'm flying kind of blind here. The closest I can find is the 180gr Speer RNSP which requires a C.O.L. of 3.07. When I increase the cartridge length to 3.07, it won't fit and the bolt won't lock up.
So I slipped a wooden rod down the barrel as I've learned to do here, made a mark with the boolit in the chamber and another mark with the bolt closed - giving me a C.O.L. of 2.930 - .164 more then I've got at the cannaluer.
So is this a significant difference? Should I be concerned that following the boolits design makes it slilghtly shorter than is called for?
If anyone has loaded their Enfield with the 312-185, I'd love to hear from them. Thanks for all the free advice you folks have given me over the years as I've lurked around here.
