That's pretty sick, Harm.  You should call Tony and ask him about doing one of your SIG's like that.

    He said he's going to do a couple more to see how fast he can do it, to see if it's feasible now that he knows what he's doing and then he'll post up on that forum about it.  If he starts doing them I'll be adding another 556 to the stable and getting the treatment!  It sounds like it's pretty likely though, he says the 556 takes just minutes longer than an AR to do the whole conversion, and it's much less time than the AK or Mini 14/30.

    That sounds encouraging.  We need to get you loading your own so you can be ready.

    hmm, i always did want an AA-12. are those covered by a class 3, or are they "unsporting/destructive devices"?

    My guess would be since they are full auto and a post 86 design you will be out of luck trying to buy one. But one can always dream.

    I think my point was lost  :bash damn ADD

    My point is that a semiauto slug gun, firing .45 saboted bullets is ballistically, a semiauto 45-70.

    I dont understand how something not designed to fire shot is considered a "shotgun".
    I also dont understand how, despite having a rifled barrel, it is not called a rifle...anyway, back on track:
     a semiauto rifled slug gun can fire 300-400+ grain bullets at 1600-1900 fps, to me, that is essentially a semiauto 45-70 without having to spend 1000s of dollars for a custom made semiauto.   :hide

    Sorry Nelson,
    That seems a little light and a little slow to compare it to a 45-70.

    Oh didn't realize I'd link'd to magnum loads.  Side question since I didn't realize there WAS a 45-70magnum, what guns are chambered in it?  I honestly don't think I've seen a magnum one before.  Or is this just the names for the loading?  I ask because I used to buy my 45-70 hunting ammo from Buffalo Bore.  It was pretty potent stuff.

    Not a chambering, just a name to seperate this +P+ load as you suspected.  I don't personally load the 1895 Marlin to that level, as it is the point people start to have trouble with the locking bolt and recesses.  The couple hundred fps isn't worth it.  Now in a Ruger, High Wall repro or 1886 it is a different story.

    Only1 - would that be a difference in power levels whether the Marlin 1895 was new or not?

    Right from the manufacturer's site:

    We use only factory stock firearms in recording velocities, so that you get true, actual field velocities with our ammo --- not exaggerated test barrel velocities

    All .45-70 Magnum loadings are intended for use in the following firearms:
    All Marlin Model 1895 variations made since 1972
    Browning Model 1885 and 1886
    New England Arms Handi-Rifle
    Ruger #1 and #3
    T/C Encore
    Shiloh, Christian and Pedersoli Sharps
    New Production Winchester 1886

    The 500 gr. load uses a dual diameter, bonded core bullet by Alaska Bullet Works. The bullet diameter in front of the crimp groove is .449 inch, while measuring .457 inch on the shank. This dual diameter allows for reliable chambering in rifles with short or no throats. This is a non-expanding Full Metal Jacket bullet designed for the deepest penetration on the largest game animals. This load is safe for use in any firearm designed for the other BBA .45/70 MAG. LEVER GUN cartridges.

    When using Marlin Guide Guns with 18.5" barrels deduct an average of 50 fps from the charts below.

    New as in since 1972, or new as in current production?  The "new " 1895's are certainly stronger than the pre 1917 model of the same name.  And while there have been refinements since the 336 based 1895 was introduced that increase the strength of the current model in some ways, the elastic limits of the parts involved is pretty much the ultimate limiter and hasn't changed much.  

    We aren't talking immediate catastrophic failure, but a shortening of the rifles useful life as the action gets progressively more loose.
