    what is the comparrison between a .41 mag hand gun round and a .410 slug fired at 1830fps from a pistol grip shotgun. i would think the .410 has more energy behind it. am i correct?

    The .410, IIRC, has energies about like a .357 mag. At 1800 fps with an 88 grain bullet, I indeed get a bit under 650 ft lbs, about a good .357 load out of a 4 inch barrel. However, the slug has pathetic sectional density and the .357 would outperform it in penetration and would, of course, expand. The .410 ain't worthless, but not exactly the answer to all self defense.

    However, it CERTAINLY is no .41 mag! The .41 can be handloaded with 200+ grain bullets to 1000 ft lbs, .44 mag territory. I'm not real sure what factory loads are available. But, the .410 can't compete with the .357, much less the .41.

    Bare in mind, 1800 fps, if that's the published ballistics for the slug, is out of a 28" barrel, not one of the new Taurus revolvers in .410 or an sort of handgun length barrel. To get serious about shotgun self defense, step up to at least the 20. I like 20 gauge, good ballistics in the slug and good fires a decent load of 20 pellets of #3 buck (.25 caliber) shot and it's far less recoil than a 12 if the little lady needs it while you're working nights.

    The federal .410 hollow point slug launches a 109 grain .41 caliber slug at 1775fps. Their 180 grain load for .41 magnum launches 180 grains at 1240fps. Their 230 grain load is launched at 1080fps. While the KE measurement for the slug is higher, I believe the drastically increased sectional density of the .41 magnum puts it in whole different class. Also, the .41 mag is fired from a rifled barrel, so it should be more accurate. I don’t know what kind of sights are on your shotgun, but if there bead sights, The .41 mag should have a better sight picture.

    Judging a cartridge purely on KE is often deceptive. Taking a look at the KE, momentum, sectional density, bullet construction, velocity, rate of twist, and the diameter, will allow for a much more through interoperation of a cartridges external and terminal ballistic effects.

    Apples and Oranges in the same diameter. There has been some work on heavy slugs in the .410 in a heavy gun like the NEF/H&R but the standard factory loadings don't even come close to the .41Mag.

    I love both the .41Mag and the .410, both high on my list of favorites and I reload for both and have tons of fun with each.

    thanks for the replies, i thought it would be close to the power of a .41 mag, i didnt realize the grain was that low. the remington box just says its 1/5 oz.

    still the power close to a .357 isnt too bad.

    1/5 ounce = 87.5 grains.
    I agree, lighter than I would have thought.

    "...am i correct?..." Nope. Factory .410 slugs weigh roughly between 87 and 110 grains. The .41 mag starts at 170 grains. Mind you, the velocity will change out of a smooth bore. The accuracy will be gone as well.
