    trying to find someone who is currently shooting a series 160 TDE/Hi Standard .357 automag. Where they get their ammo the .357 AMP. Is the
    .357 Sig the same as the bottleneck cut down .308 case for both the .44 and the .357 AMP. I can buy .44 AMP from Cor-Bon for my series 180 automag but cannot find any .357 AMP!

    I have no idea where you can get .357 AMP ammo.

    It seems it is a reloading proposition now days.

    This company lists it, but thats all I know about them:

    .357 AMP is nothing at all even similiar to the .357 SIG cartridge.

    Cases can be formed from 30-06 or .308 rifle cases, then neck reamed to reduce the excess neck thickness.

    I was under the impression that all of the AMP cartridges were strictly hand-loading propositions these days. Interesting that the .44AMP is still available as their must be enough folks buying the stuff to make it a feasible offering.

    I’ve loaded thousands of .357 AMP rounds. It’s a handloading deal as far as I know. You can buy .44AMP brass from Starline and just run it through a .357AMP sizing die.

    My favorite .357AMP load was the 150 gr Sierra JHP over 20.5 gr of WW296 for 1850 fps in an 8 ½” barrel.

    There is a forum out there for automags. They talk about the 357 Automag a lot on it.


    Had to show the big guy.

    Well, automagj, you just cost me a whole lot of money. :mad:

    I used to have .44 and .357 AutoMags, but was stupid enough to sell them about 30 years ago. I got 4 times what I'd paid for them, but still ....

    Now you got me excited about AutoMags again and I bought a .44. Gotta buy dies (expensive!) and brass (expensive!!) and dig out my loading data and work up new loads and go through the entire process again.


    :D :D

    I've owned both the 357 and 44 automags in the past, in fact i owned two of the 44's. I "think" i still have all the RCBS dies to make the cases and load them.

    I'd have to look for the die sets, but if anyone wants to buy them, pm me...

    I don't miss those guns at all...

    Man oh man I have always wanted one of those. I passed on a cased frame with a 44 and a 357 barrel. Was too spendy then and they remain too spendy now.

    Seriously neat guns though.

    Dr Rob. I was the same way and I just bought it now 25 years ago at a spur of the moment and a drop of weakness of the knees.

    Mine is never fired and still pristine. When I bought it I could not afford to shoot it and now 25 years later parts are too hard to come by to risk it. So it sits in the safe and I get to say "I got one" when threads come up. Beyond that it is kind of worthless actually. Don't get me wrong that I don't like it. I am just thinking about it practically.

    Buying a gun you never shoot seems like marrying a nun. It's there, you know it there, but you never get to "really" enjoy it.
  13. Peter M. Eick

    Peter M. Eick Well-Known Member

    Actually I have a bunch of them that are unfired.

    Yes I can see the analogy of the Nun, but if you own the whole cloister, why test every one?

    I have a 38/44 Transition HD that has never been shot. A 1950 38/44 OD that has not been shot, 44 automag, P7PSP, SW 41, etc.

    When you have 22 38/44HD's why shoot them all? The unfired ones are just fine. Same with the P7PSP's. If you have 3 shooters, why shoot the 4th?

    The 44 AMP is unique that I would like to shoot it, but I am not willing now to risk it. For that same reason I am not willing to buy another one as a shooter.

    Well, in the interest of making the analogy a bit more honest...you own them all but cannot test any of them.
    How you like them apples? :)

    I do not, and will not, own anything that I cannot/will not shoot.
    Perhaps your budget exceeds mine, or your parameters are different.
    Which is fine...differences of opinion make life interesting.

    Best regards, Rich

    aoutomag ammo

    Everyone! Thanks for the imput. Japle-it's worth it-isn't it? Peter I since found a manuel just like the ones you showed and yeah a picture of the big guy always lights me up. In the past weeks here is where I am. I have just acquired a set of dies for the 357AMP and think I found some 44 dies as well. I have been saving my 44AMP brass from the Cor-Bon ammo to form into the 357-the reason is the wall thickness or "wall thiness" is noticeably thinner than the wall thickness of the Winchester and Remington .308's I have been cutting down and trimming. I have some Starline 44AMP brass back ordered. I suspect the Starline brass will be very thin as well, I load Starline brass for my .475 Wildey and it is thin. I was at gun show recently visiting with an old ammo reloader. He used to load 357 AMP years ago and was explaining how he had to heat the brass and then blanch it to soften it-form it then heat it again but not as hot and cool it down to harden it - Japle help please! I am going to Tulsa this weekend to the Wanenmacher's show and do some more investigating. I hope to be about two weeks away from my first round. I just saw a .41 mag barrel on gunbroker - check it out. I better leave that one alone for now. Again, everybody thanks for the feedback, take care. aoutmagj

    You only have to anneal reformed military brass. CDM and Starline don't need it.

    I used to set my military cases mouth up in a shallow pan, set it under the broiler and fill with water to the top of the case. Broil until the top half inch of case is exposed, then turn off the broiler and let cool. I don't recall ever having a split case neck.

    Finished my first round of 357AMP loading and test firing. I formed the bottle necked brass from the cut down Winchester 308 I previously prepared-the remington 308 brass will be used for the 44 AMP. Using Blue Dot and CCI 300large pistol primers for all four seperate loads. The four combos were: Hornaday JHP 110 with 19.0 grns; Speer 125 JHP with 18.0 grns;Hornaday 140 JHP with 17.0 grns and Hornaday 158 JHP with 16.0 grns- Japle - I just picked up some WW 296 and will look for some Sierra JHP this Saturday at a local gun show-what large primer do you prefer? The 110 JHP was my favorite so far just because of the flame it put out, it actually scared a couple shooting next to me. Then the range of testing up to the 158 JHP didn't really feel liked it kicked as much -just the flame went down. I also brought along a Desert Eagle in 357 Mag shooting Hornaday 158 XTP to compare. The DE is going to be the safe queen. I have a box of 357 AMP that was loaded by Beals a long time ago, the brass is actually split at the top down to shoulder so it of course it will never be used except for comparison. If any one would like a round I would be glad to send one to you. Best Regards, John

    I used to use CCI350s and that's probably your best bet. I have a few thousand WLP primers that say "Standard or Magnum Loads" and that's what I'm using right now.

    The .357AMP was famous for wiping out all the grass and low brush for 20 yards with the blast and flash. :eek:
    At a silhouette match 30 years ago, I was shooting my .357AMP from the "Creedmore" reclining position. The muzzle was only a foot from the ground. There were clumps of grass in front of the firing line when I started, but none when I finished the 40 shot course of fire. The blast had produced ripples in the dirt, making it look like a view of the Sahara from 40,000 feet.
