Update--I loaded some of the 100 grain round nose flat point bullets. I started at 3.0 grains of W231. Then 3.2--3.4--3.8--4.0--4.2. The toggle would not work with 3.2--3.4, but started to work with 3.8. 4.2 worked well. BUT the bullets were key holing at 7 yards as the bullets rear does measure .309, but the rest of the bullet then abruptly tapers to .306. I am going back to the few .90 grain hollow points I have and will post those results soon.
