Do Hard Cast Bullets Cause Leading?

What are hard cast lead bullets?

Hard cast bullets can be formulated of numerous alloy mixes (antimony, silver, tin, etc) containing some lead, but the alloys make the bullet much harder than pure lead..

What is lead fouling?

Bullet-metal fouling is the result of pushing a relatively soft metal (or metal cased) object down a relatively hard bore at high speed. … Metal—lead from cast bullets or copper from jacketed bullets—is rubbed off the surface of the bullet and is left inside the barrel.

Can a bear skull stop a bullet?

Since the spinal cord is so small, it makes sense to aim at the brain. But bears have thick, strong skulls shotgun slugs or even rifle bullets may not penetrate. … A bullet striking this area has the greatest chance of penetrating the skull, hitting the brain and stopping the attack immediately.

Are lead bullets more accurate?

Lead is a dense and heavy metal. This increased weight means shots have more momentum, velocity and even more accuracy, allowing lead bullets to deliver a better upset at long range.

What is a lead bullet?

Lead Alloy bullets and Bullet Rounds A lead bullet is a projectile. … Low speed bullets such as those fired from black powder, or muzzle loading firearms have been generally molded from pure lead, also know as musket lead. Such bullets are still made today for use in antique and replica fire arms.

Are hard cast bullets bad for your gun?

The fundamental problem with hardcast bullets is that at low pressures and velocities they will not “slug up” and seal the bore — so you don’t get good forward obturation. Gas can squirt past the bullet, and that leads to gas cutting, lead fouling, and inaccuracy. Most commercially cast pistol bullets are too hard.

Can you shoot hard cast bullets in a Glock?

HARD CAST BULLETS DO NOT FOUL However, in my experience, quality hard cast bullets won’t foul a Glock polygonal barrel or any other type of barrel but lead bullets normally will.

What does hard cast mean?

Hard cast is a generic term that was used by bullet casters to differentiate their bullets from the soft swagged bullets as offered by Hornaday, Speer and Star bullet works as well as other swaged bullet makers.

Will lead bullets hurt barrel?

And they do not damage or hurt the barrel any worse than jacketed bullets. At the slow velocities we use, barrel leading is rarely a problem when using a good quality hard cast bullet. Depending on the bullet hardness, serious leading doesn’t occur until you push it past 12- 1500 FPS.

What causes leading in a barrel?

Gas escaping around the bullet in the chamber throat is the cause of most revolver leading. Lead fouling used to make me crazy. Fortunately, a part of my brain retained some degree of sanity and worked toward understanding the causes. Most of this column covers leading in handguns, specifically revolvers.

What is a Linotype bullet?

Linotype metal is a eutectic alloy of 3% tin, 12% antimony, and 85% lead. It is a very satisfactory alloy for casting most bullets. However, bullets from Linotype alloy tend to be brittle, and not suitable for some game hunting.

Is a 10mm more powerful than a 357 magnum?

10mm vs. 357 Magnum is a powerful cartridge, but in this case it takes a narrow 2nd place to the 10mm Auto. 10mm generally packs higher muzzle energies thanks in large part to the larger bullets. Even with similar bullets, however, it appears the 10mm does slightly better.

Why do Glocks not have lead bullets?

Glock makes it clear that they don’t want you using lead in their guns and their reasoning will keep you out of trouble if you don’t know pure lead from linotype. … If you do make the decision to use lead in a Glock factory barrel, be sure that you use a bullet of sufficient hardness that uses a gas check.

What kind of lead is used in bullets?

For even higher-speed bullet use, jacketed coated lead bullets are used. The common element in all of these, lead, is widely used because it is very dense, thereby providing a high amount of mass—and thus, kinetic energy—for a given volume.

What is the difference between hard and soft lead?

The softer the lead, the darker and broader the marks it will make. Hard lead usually has the designation of a number and the letter H. The higher the number, the harder the lead is. This means it will make lighter and thinner marks and will require more pressure to make a dark broad mark.

Why are lead bullets bad?

Lead’s availability, density and malleability have made it a cost-effective bullet material for centuries. But lead bullets can lose half of their mass on impact, leaving hundreds of tiny fragments both in the meat hunters take home and the entrails they leave behind, which are a food source for many wild creatures.

What does lead fouling look like?

Lead fouling looks like streaks of white but if it’s thick then it can look like flakes of metal.

What is a paper patch bullet?

Paper patched bullets are made by winding a piece of paper, usually twice, around a lead bullet. … However, the lead bullets I make for patching are designed to fit the diameter of the bore, not the groove, which means the paper patch is at least partly cut by the rifling as it travels up the barrel.
