The Rifles Slug was cut open and the slug was exactly .40 inches in diameter and weighed 96 grains.

It had a white powder as a filler behind the slug.

This was surprisingly light to me.

Some have mistakenly said, "Getting hit by a .410 slug is like getting shot with a .41 caliber pistol."

But a .41 Magnum lead bullet weighs approximately 210 grains, over twice the weight of this slug.

The Remington data says it leaves the muzzle at 1,830 fps out of a shotgun barrel.

This shorter barrel will have less velocity.

Let's see how it does.

It penetrated 2 1/2 jugs or equal to 7.5 inches of BG.

Again, well short of the 12 inches minimum required for a defense load.

The soft lead projectile was flattened out quite a bit.

Well, how about a .45 Long Colt cartridge?

I tried an old Winchester Silver Tip that I had.

The recoil was "brisk" compared to the .410 ammo.

It penetrated 5 jugs, or equal to 15 inches of BG.

Plenty of penetration, but the expansion was not very good, a problem with this particular bullet.
