    IS there any reason not to load a full weight .41 magnum jsp/jhp bullet into a 410 shell for serious work?
    I just ask because the normal .410 slugs are under that weight and well, the boxes from winchester list them to be good for deer hunting at 100 yards if your brave enough to try.

    "...serious work?..." What would that be?
    It'd cost you more for jacketed bullets that would give you the same accuracy as a slug. They likely wouldn't expand at .410 slug velocities either.

    I'm quite sure it would tumble and not give any accuracy to speak of, plus if your running it through a full choke it will deform anyway.
    I stack 3, .380 balls in the 410 for a defense load out of a NEF single barrel that's been shortened to remove the choke.

    I really don't recommend using a 410 for deer, although I know it's been done. It's just too marginal unless your almost on top of them.

    41 mag is designed for way higher pressures..... i thought it was 45 colt lead slugs you could shoot outta 410's?......i was lookin at a single shot new england arms .410 but the end of the barrel looked way too tight....might there be a choke? or could i still occasionally shoot 45 colts out of it..... roughly the same operating pressures too.

    I had this thought also. I was told that the .410 bore was originally a rifle? But then like what was said above...shooting rifle bullets through a smooth bore is in the question.

    1858rem, if it's chambered for 45 Colt then it'll shoot 410 safely, but not the other way around. My 410 barrel end measures .413 with no choke and the 45 Colt bullet measures .452 so it could be detrimental to your health especially if you have a choked 410.

    Don't do it!

    Shotshell cases are not designed to handle the pressure you would very likely get with .410" Jacketed bullets.

    .410 rifled slugs weigh in the 85-90 grain range.
    .410 pistol bullets range from 170 to 220 grains!

    Shotgun slugs for the .410 are hollow-base, so they can squeeze up/down to fit whatever bore & choke they are shot in.

    The hollow base is also the only thing that keeps them flying point first, like a shuttlecock.
    Without that, or rifling spin, you will have no accuracy at all.

    A .41 Mag bullet would begin tumbling right out of the muzzle of a smooth-bore barrel.

    A 1/2 oz. load of shot weighs approx. 218gr so the weight would be ok. (210gr ?), The problem is the basically unguided 41 cal. slug being sqeezed through the choke.
    I know factory 410 slugs are light and pretty fast out of the muzzle due to the weight, but lose velocity rather quickly.
    My 3 ball load has a combined weight of around 240gr and I know I'm pushing the envelope on the pressures, but my NEF is solidly built and digests these loads without a hitch. I'm guessing around 1100-1150fps. IMO, it's the best way to make the 410 a viable defense weapon.

    well.....from what i remember when i reloaded shells(now shot is too expensive lol) regular shot ....straight buck shot... and buckshot with baffling all flow differently creating a wide variation in pressure, especially the buckshot with and without baffling, so i imagine since the slug wont be as easy to change the bore contact area as shot which could flow out and relive pressure, the slug may raise pressure significantly. ill check an see if there is any online data for slugs and i think lee makes a mold so you can load slugs into a regular shot wad. my guess is they use a low weight to get the extra velocity 218g shot@1200fps= 699fpe and 1/5oz slug@1850= 665fpe......umm well i have no clue then!!:scrutiny::confused:

    The 410 works on 14,500 psi maximum. The 41 mag works on 35,900 psi maximum. About 1125 fps for both. The shot/bullet are both about the same weight. Less pressure for a plastic shotcup/slug of pure lead. The 41 jacketed bullet would fill the bore an make 3 times the pressure of the shotshell. KABOOM. As RC said
