Being a .45, the round balls are either 127.xx gr or 133.xx gr. depending how pure the lead is I pour them with and how accurate the Lee molds are that mold them. I won't be using any conicals or maxis. It has a 1/66 twist.

After I aasked I thought there wouldn't be much of a difference in round ball projectile weights, at the same caliber.

After I aasked I thought there wouldn't be much of a difference in round ball projectile weights, at the same caliber.

I see is as appx .75 - 1.0 gr per thousandths" of diameter. .440" compared to .445". Not a lot of difference in round balls.

Here is an interesting link...just found it.
