Keyholing: 9mm lead 147gr. rcbs flat nose/flat base
My flat nose RCBS ww 147gr.bullets look great and fly like a tipped pass from a bad thrower. I had temporarily lost my source for the functional/useable 136gr rnl bullets I am using now. So I had to do something...I ordered the $67 mold and cranked out 1,000 lead bullets...They suck!
I got my 136gr. source back so I can gladly say I am ok again BUT STUCK with a mold that I can't use.
The problem is KEYHOLING even at 20'. I tried N-340' N-350 and aa#7 also .356, and.355...nothing helps not lighter/heavier crimp or long or short OAL. I am loading pretty light stuff, like 133 power factor. Who wants to chime-in, anybody who loads lead 9mm from wheel weights ??
