boolit shape??

I've been trying to learn more here, but, I don't understand the why's and wherefores of boolit shapes.

A jacketed bullet can have a long, slender shape with minimal bearing surface, and it seems to fly straight. But from what I've been reading, cast boolits seem to need a long tubular shape to fly straight. How come? I've read that they can enter the rifling crooked, and that detracts from their accuracy. Doesn't the same apply to the J-words? Can anyone help me understand this better? Thanks.

Main reason jacketed can successfully use a slender nose is due to the jacket preventing nose slump caused by initial accelleration forces which deforms a cast boolit causing very erratic flight and extreme accuracy loss. There's a lot of other factors as well, but this is a major player in shape design choices.

An old Cherokee was teaching his grandson about life. "Inside me two wolves fight," he told the boy.
"One is evil - he is anger, envy, greed, arrogance, self-pity, resentment, lies, false pride, and ego. The other is good - he is joy, love, hope, serenity, humility, kindness, generosity, truth and faith. The same fight is inside you - and every other person, too."
The grandson thought for a minute and asked,"Which wolf will win?"
The old Cherokee replied, "The one you feed."

Because lead is much softer than copper, when it enters the barrel at an angle it deforms and becomes canted relative to the barrel. When this happen with a copper jacketed bullet the harder copper causes the bullet to "self correct" lessening the effect of the cant. Lead also "self corrects", but only a very small amount. The harder the alloy the better the "self correcting" ability.

The BHS of copper jackets(it is not pure copper; it's called Gilding Metal) is 114, give or take. The hardest you can get a lead bullet, as you probably know, is about 30. And then there are steel jacketed bullets...
