Time to continue load development with my .44-77.

[Kurt]

I like to keep mine close to 45%. Some of the money bullets I have in the .45 caliber that are close to 50% just don't do well for me in my 18 twist rifles when the winds get above 15 mph coming at 2 or 10 o-clock. I like my hemi center at around .130" and that shortens the ogive where I like it.
The smaller the Hemi the longer the ogive the faster the twist needed or more powder if the twist is less.
I have a 14 twist .40 I can use a 50% that has a hemi like Brents .45 prolate that shoots well but use it in the 16 twist it has problem at midrange.
