patched round ball w/1:28 twist question.
A crazy thought has been going through my head while at work of trying to find a round ball load for my .45cal CVA Kodiak Pro. Would the round balls work spinning that fast or would the fly off to god only knows where.

I have a round ball formula that seems to actually work. I don't know where it came from but have had it for years. The forrmula is for using GOEX 3-f and PRB. This is a starting load.
caliber X rate of twist X 2
Example: .45 x 28 x 2 = 28gr
As I said, using this formula I would start at 30 gr with your rifle. This works for me on everything from my little .32 to my .58.

There is an other formula which is the one my Grandfather taught me
"one grain per caliber as a starting point and go up 5 grains at a time until the group opens up" I know this works well for me with every twist from 1-80 to 1-38 I have not tried it on 1-28 but would expect it to work. Lee
