    Nowadays the 586 is considered a somewhat rare Antique. My L frame is the model 620 which features a tensioned barrel with S&W's ECM rifling which is a variant of polygonal rifling. As for accuracy, I've tested mine with a scope off a sandbag rest and it is a sub 1 moa handgun.

    @Spohr-shootingPrecision I'd love to T&E one, especially w 9mm swappable cylinder like all my Taurus 692 videos. Actually pretty slow velocity from 3" so that says the powder the critical duty uses is optomized for 4" barrels. You will see better performance from 3" from hotter Federal or Remington 125 sjhp, maybe Critical Defense, or golden saber which are mid recoil defensive loads. Be nice if you at end showed calipers of expansion in inches of each JHP. Cheers, the button swappable cylinder I first see on a Beretta Prototype on tfbtv I think that may have ended up in Brazil and to the Taurus 692 50 years later....what is your production goal cylinder gap to forcing cone?

    Hard cast lead ammo is fairly common in .357/ 38 calibers. Will this result in fouling in the polygonal barrels?

    Give me a rifled barrel any day that will shoot anything. Polygonal barrels don't shoot just anything. I have one polygonal barreled pistol and I don't like it but it is what it is without changing the barrel to a rifled barrel. I can shoot any kind of jacketed or coated lead bullets with it but it will not shoot bare hard cast lead. A polygonal barrel squeezes the bullet rather than cuts it and the squeezing pushes lead instead of cutting it. So rather than being held by rifling cuts it skips along the hills that leaves lead that was pushed. The excessive lead builds up quickly in the bore. This is why polygonal barrels need jacketed or coated bullets to provide a bullet seal. Higher velocity and a wider range of bullet lengths can lead to problems with polygonal rifling. Rather than suffer all these problems, a rifled barrel is better. These disadvantages outweigh the advantages of less friction with jacketed/coated bullets and ease of barrel production over rifled barrels.
    When you fire a lead bullet in a polygonal rifled barrel, which has shallow hills and valleys instead of grooves and lands, the lead bullet isn't gouged. Instead, the rifling squeezes down by the rifling, and the lead bullet will frequently “skip” over the hills. This leaves lead deposits throughout the barrel.

    Would a conventional rifled barrel with shallower 'grooves' come closer to match the polygonal test results?

    • @Paladin1873
      @Paladin1873 11 місяців тому

      Rumor has it that polygon rifling can increase velocity over conventional rifling by as much as 5%, but it really depends on the individual barrel, cylinder gap, and cylinder construction. The tighter the tolerances, the higher the theoretical velocity you can achieve due to less gas leakage. However, tighter tolerances in the bore could induce more drag if peak pressure is reached before the projectile exits the muzzle. Also, you could reach a point of diminishing returns where increased pressure becomes dangerous. This concern probably applies more to rifles than handguns.

    • @Paladin1873
      @Paladin1873 11 місяців тому

      @@TrollMeister-s6n The question was about velocity, not leading. I can't speak to why a government agency might specify conventional rifling, but any barrel will accumulate lead deposits, copper fouling, and/or powder residue over time. All that differs is the rate of accumulation and its affect on accuracy or functional reliability. If leading becomes a problem, a tool such as the Lewis Lead Remover can quickly correct it. Some manufacturers caution against using lead bullets or reloads, but this is more of a CYA legal tactic than a true safety or reliability issue. For example, when I went through the official Glock Armorers Course, the instructor told us about a range pistol he examined that had fired several hundred thousand rounds of lead projectiles without cleaning. The bore was so clogged with deposits that it was squeezing the bullets down to a smaller caliber, yet it still functioned and had not bulged the barrel. He removed the lead and it regained its former accuracy.

      I wouldn't do it either. I do think it's most likely to damage a revolver with a loaded cylinder and possibly with lower grade steel used for the crane and lock parts. There's quite a bit of shock through all that when firing and they can't get away with too mild of a grade steel even on the cheapest revolvers. Of course if you bend something you can always straighten it back in that case. Maybe not on the MIM parts which some are almost all MIM except the barrel.
