View Full Version : 3" .410 slug would be equal to what pistol?

Just curious.....

Been shooting some 1/5 and 1/4 oz. 3" slugs out of my little shotgun. These things seem to jolt one of my steel plates more than my Glock 23 (40sw).

Power-wise, (or I guess, ballistically) what would a .410 slug be equal to when compared to pistol calibers?

According to my figures, those are firing either 110 or 87 grain slugs. Pretty light for caliber. Unsure of the velocity of the slugs, but I would think theyd really have to be scootin to beat a 40.

They run around 800 ft lbs so .357/10mm plus. The Brenneke slug is very good choice. 110 grains at 1,755 fps and 781 ft lbs. More gun than most people realize.

I just love the .410 slug; it will reach out and touch you with prejudices and determination. The Judge shoots the .410 and the .45 out the same barrel.

This guy (http://mcb-homis.com/slug_410/slugtest/index.htm)tested four .410 slugs, three of which are the same weights as the ones you were shooting. Muzzle energies were between 704 and 722 ft-lbs, which is more than most commercial .40 S&W loadings fired from pistol-length barrels.

Thanks for the link. That "guy" got 1,065 ft lbs with the Brenneke. The terminal performance was awesome. The slug was intact at over 2,000 fps. So we are well beyond .357/10mm, right below .41 mag

I figured theyd be much more sedate than that, I stand corrected. Still seems light for caliber to me, but certainly nothing to sneeze at.

Brenekke lists their 3" Magnum .410 Slug as 114gr at 1755fps for 781fpe energy. By comparison, Reminton lists their .41 Magnum JSP loading as 210gr at 1300fps for 788fpe. So, energy-wise anyway, it would be pretty comparable to a .41 Magnum.

Bear in mind, however, that energy is only one part of the equation. The heavier bullet of the .41 Magnum will likely give substantially deeper penetration than the lighter, faster .410 slug. Also, the Brenekke slug is very hard lead which is designed to deform/expand little or none. Loaded with an expanding bullet, the .410 slug would likely have very shallow penetration due to its light weight and low cross-sectional density.

Six plus inches of penetration in wet newspaper is nothing to sneeze at. About the same as OO buckshot from a 12 guage which goes six inches in wet newspaper. For bad guys and deer, the Brenneke slug would work real good.

Interesting. I knew something was going on with these judging by the way it hammered my target plate. I just started reloading with 9mm pistol cartridges. As expensive as .410 shells are (and considering how accurately my shotgun shoots the 1/4 oz slugs) I'd like to eventually reload and custom handload these. Slugs, buckshot and shot.

Speaking of reloading for these.....I noticed that Midway sells full length brass cases. Magtech brass. Anyone here use those?


Thanks for that link.

Hodgdon Cartridge load data online shows several .357 cartridges that use a 110 grain Hornady XTP bullet traveling at velocities near or faster than 1800 fps (these specs are shown in the handgun section, not in the rifle section, in case anyone wonders), so just in terms of mass and velocity, that's probably as close as you'll get. This would also give them about the same muzzle energy.

Of course, the different bullet designs/diameters will change their end performance.
