    Regarding bullet size science

    Respectful to all regarding the right bullet size. Fact: In a "breech loader", pushing something down a barrel is not the same as having a big explosion do it! Lead is soft. A lead bullet is compressed like a sponge from an explosion behind it. Smaller bullets will fill the grooves completely upon this high pressure! Just look at a undersized bullet after it is shot. The lands compress and displace the lead even more and also aid in filling the grooves. A bullet is not the same size in a barrel under pressure as it is after it exits it, either. Just to clarify this, a undersize bullet is something less in diameter then the groove diameter, not the land diameter. Friction is not your friend. The less the better. Lubrication matters, Caps matter, Nipple hole sizes matter, Powder type matters, Size matters & Lead hardness matters. Some number of these in combination will make a shooter, a great shooter. These are all the basics. I was thinking of attaching this to a post but decided this was a better idea.

    Well Bruce, you said a lot but didn't tell us anything. You must have some politician blood in your veins.

    John is a cold man, but he has a point. Those of us who are shooters should know all of this already. And it all comes down to " feed the gun what it likes". That's why we spend range time working up loads (at least that's where we should start.) We should be happy we're shooting black. Think about the modern guys. Bullet, case, powder, primer seating depth, it goes on and on. I'm not that bright or patient.

    Everyone has an opinion. Here's mine.

    How many times have you heard someone say that such and such a Minie has too thick of a skirt and won't expand into the rifling properly? If 50 some odd grains of powder wont expand a Minie skirt (Yeah, pun intended...), I find it hard to believe 30 or 40 some odd grains is going to obturate an undersized flat based bullet in a breechloader. Yeah, it ain't exactly the same thing, but still.......

    Again, just an opinion.

    Ok

    So what?

    Did someone tell you something different and you want to come on here to make a point or just rant?

    Lot more factors involved than just what you stated.

    Rant? Really? I haven't a clue where THAT came from.

    No ranting on my part. Sorry you perceived it that way.

    Personally, I read the OP as random musings put to print, and nothing more. I read it, shrugged my shoulders, and moved along.
