    I have a EAA WINDICATER 357, and am wondering if I can fire 38 super through it. Any information will help.

    Yes. You can shoot 38 auto ammo in a 38 Super weapon, but you cannot shoot 38 Super ammo in a 38 auto weapon. 38 Super ammo is much more powerful, and it would not be safe in the 38 auto weapon. The higher pressure of the Super would probably severely damage a 38 auto weapon. The 38 super weapon is built to handle the higher pressure, therefore it is safe to handle both 38 auto and 38 Super ammo. If you are using a particularly light load of 38 auto ammo in a 38 Super weapon, you might have some short stroking problems with reliability because of the heavier recoil spring. I have been shooting 38 auto ammo in my 38 Super weapon without any problems. Just be sure it is not the other way around. You could seriously hurt yourself.

    arent you going to have case length issues and mag spring tension and main recvoil spring issues to contend with? lighter loads, may not recycle it.

    Yes. I've been doing it for years with no problems. The gun is a factory Colt .38 super, pre WW II.

    Hello "gunguy30_06"[:)]

    1. If you look in "Cartridges Of The World" by Frank C. Barnes, you will find that "dimensionally" the cartridges are the same, so you can fire .38 Auto in a .38 Super, but not the other way around. The .38 Super works at much higher pressures than the .38 Auto.

    2. Like "robkelly2242", I have a factory Colt in .38 super, pre-WWII, the only Colt I own, and I also will grab up .38 Auto at a gun-show in a New York heart beat if the price is right.

    Best Holiday Regards To You And Yours[:)]
