    Ordered a 45ACP/12ga rifled insert

    a couple of these on the market , thought I would try one of the rifled ones by chiappa. They are an insert into the shotguns chamber allowing it to fire a variety of pistol ammo. The chiappas have about 8" of rifling. Anyone tried one of these? My bet is accuracy will not be overly high, the tolerances would need to be loose enough to get it in and out of the shotguns chamber.

    Hi Im In australia, so just our chiappa distributor. Whoever brings your chiappa x-calibre guns in, should have a handle on these. I think there are 8 calibres covered, you can buy separately or as a kit. Us prices https://www.chiappafirearms.com/category.php?id=23

    pistol cartridge with pistol length barrel = pistol accuracy. chuck an optic on it and you might be surprised.
    The ones I've seen have o-rings to fit the chamber, lube them good.
    Also if they don't have an index mark, make one so you can re-fit it the same every time. disable your extractors if you can.

    Mimms2, thanks good suggestions. I'll give it a run in an old D/B here for starters but was thinking about getting one more compatible with optics. Worst case I have another shotgun.
    Anyone know the options for shotguns and sighting systems out there?

    With an old break you're petty much going to have to sweat on a rail for a low mag scope/ dot.
    The rossi pomba/wizards may have had factory holes for one? And if TC have shotgun offerings they'll likely have factory mount.
    Alternatively if you get a ribbed one, a mid-bead is an easy fit, or a ghostring rear.

    ..."Prohibited parts are:
    Any part designed or intended to be an integral part of a prohibited firearm.
    Examples include: butt, stock, silencer, sight
    Any component that can be applied to enable a firearm to fire with (or near to) semi-automatic or automatic action.
    Examples include: gas block, gas tube, sub-calibre conversion kit."

    Maybe not actually in the legislature... and the above would imply that they'd only apply it to "any component to [enable near semi auto fire]" but knowing them...

    Mimms2 it does sound in relation only to gas operated actions. We have similar here I think, the legislation relates to conversion kits for handguns/semi-autos etc to fire 22LR. Might be worth any Kiwis interested checking it out with the cops or your gunstores. You might be okay.

    It kinda does, eh.

    But a sub-calibre conversion kits doesn't *enable* near semi auto fire. Like everything else around this, it's poorly written by ignorants.
    I may have read it somewhere else too, that was just the first link come up on search, I may be wrong too. See what comes out in the wash.

    nope a sub calibre conversion like this is NO WHERE NEAR semi auto fire...its a slow single shot at best...you still have to manually remove and replace rounds....these chamber inserts are nothing at all like a semi conversion kit....chalk and chainbar lube.

    Be a cool idea to use the rest of the 12ga hole as a suppressor if you could ensure insert and baffle alignment

    Subcal inserts can be very accurate depending on the type - especially the German kinds that lock into the chamber with a free floated barrel and are indexable/adjustable. The kind I'm familiar with are ~12 inch barrel, maybe 8 inch.

    Helped prove to me that accurate shooting is far more dependent on accurate sights and stable shooting platform (IE a full stock) than overall barrel length, as a pistol length insert in a 12 gauge will very easily shoots similarly to a rifle in the same caliber, while the equivalent barrel length in a pistol is a challenge. It's all intuitive really, but made me far more willing to trust short barrel rifles.

    One thing you could try with the chiappa inserts is a brass sleeve that matches the chamber dimensions. Would need to take care not to dent or burr it, but would give a good snug fit. Could also use a piece of sustarin or the like.
