I know this might seem like a simple question but....
I cast for all my handgun loads (.380, .357/38, .44, .45) and use a good mix of wheel weights for each. I quench my bullets as well. Whatever I cast seems to shoot without problems in my handguns and my loads do not seem to produce any leading. Accuracy seems good.
My question is.... How perfect are the bullets you cast? Unless mine have a significant void or dent I just size, load, crimp and shoot. I do not weigh my bullets either. That means I load a lot of imperfect bullets. Ironically, I measure every powder load on a scale, keeping the powder for each round as uniform as I possibly can.
I am an informal target shooter and shoot at 10, 25 and 50 yards. Other times I just plink for cans and steel plates.
I wish there was a way to know how much a certain imperfection impacts the path of a bullet.
I shoot for enjoyment, not for perfection. So how perfect are your bullets? How perfect do they need to be?
Happy shooting!
