Undecided on a great many things
I cut open a 55 gallon drum and started water testing for expansion for cast bullets and was very surprised with the results. All rounds are 9mm 147 grain MP mold. HP and round point, different molds
Left - Round point 147 grain wheel weight lead. No expansion at all! I was very surprised by this and my lead is a 10-11 air cooled and nothing for expansion. It is a hole poker.
Center - MP HP Mold. 147 Grain and held back shape and expanded .557 in front.
Right - Pure lead and expands the best. .779 on the expansion. BUT it shoots like crap and at 20 yards having issues staying on a pie plate.
Using N320 3.6 grains and an assumption that is is 930FPS
