Finally a break in the weather and an opportunity to get out in the garage and do some casting. I was running two moulds at the same time and two pots (a different alloy in each). One mould was a plain base and the other a gas check design.
I know the need for a square base on the plain base bullet. However, does the same demand for the squareness of bases exist for a gas check design bullets since we'll be covering-up the base with a gas check? Those of us who “bump” our bullets apply a really square base during that step. Has anyone ever done an exhaustive test to verify the differences if any between absolutely square and “almost” square bases when used with gas checks?
Just curious. Your mind will sometimes wander and cause you to question your long held “rules of thumb” regarding casting.
Thanks!
