I have no personal experience with this. What follows is information from a reputable local gun dealer. Rifled barrels are designed primarily for use with sabot slugs. Buckshot will not harm a rifled barrel because in the barrel, the plastic wadding holding the shot together will be the only portion of the projectile(s) in contact with the barrel. Firing rifled lead slugs will lead to difficult (nearly impossible) to clean out accumulations of lead in the barrel & negate the rifling because the rifling of the slug & the rifling of the barrel will not match up.
Lead floats in mercury.
It is dangerous because it can cause mercury poisoning. It can lead to damage of the brain, lungs, and kidney. As reffered to with the mad hatter in Alice in wonderland
Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
Is there a question there? If you are asking what to do, the best thing is probably to have a gunsmith remove it.
Assuming you mean a barrel that is for lead pellets, if the barrel is not rifled, steel shot will not damage the smooth barrel. If it is rifled however, steel shot will in fact damage the rifling.
Both lead and mercury are metals, physically lead is solid at room temperature, however mercury is a liquid, but chemically they are both metals. Mercury is a classified as a transition metal, however technically isn't as it doesn't not have a partially filled d-orbital in either it elemental state or as one of it's common ions. Lead on the other hand belongs to the group known as the poor metals.
Depends on the age of the barrel
Lead would float in mercury, as it is slightly less dense. (11.3 g/cc for lead, 13.5 g/cc for mercury)
Firing lead shot through a slug barrel will not damage the barrel. The rifling will distort the shot pattern and you will get less than desireable results.
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide
Yes ..mercury ie heavies then lead
