I knew it but I did it without thinking.

A 9mm shoots a JACKETED .355 diameter bullet. Cast bullets should be .001 larger to oburate the bore and shoot more accurately.

Well, dummy me cast 40 pounds of 9mm 120 bullets and sized them all .355. I also loaded 900 of them. Well at 20 yards they keyholed 50% of the time and nary a one hit the bull I was aiming at.

I will now remelt them all and size them to .356 as I have done with thousands of others. Why I did .355 will keep me awake at night.

All 900 rounds were BLASTED out of a AR-9 with 32 round magazines. It did not take long but that AR-9 is one filthy beast.
