Trimming .308 to make .44 AMP brass
« on: May 03, 2010, 02:21:03 pm »
Hey guys. Now that I have a car payment and a Delta Elite I'm nickel and diming I doubt I'll be able to jump on some .44 Automag brass even if it were available. Somebody actually DID have some available a month or two ago but I couldn't afford to put gas in my car then nevermind jump on 500 rounds of brass.

So I'm forced to go old-school.

That means trimming down .308 brass. Now I don't even have the proper reloading accessories yet. I'll be using my friend's Dillon but that's neither here nor there. I just want to trim the brass down to 1.298" so it will be ready when I'm ready. And as simple as that sounds, I want to make sure I'm doing it right. Not like some moron with a tiny hacksaw holding the case unsupported with my left hand, my tongue sticking out the side of my mouth with eyes focused in intense concentration...

Please list tools or any helpful accessories. I already know I'll need calipers but is there a specific kind of caliper I need? I'm a total cherry when it comes to reloading nevermind trimming brass so please consider that in your replies to me!  :hide

Oh, yeah. And step by step directions. Important, that.

Thanks guys!!!

    This, plus this:

    and a cheap drill press will get you close.  You could use any trimmer or even the Lee tools to finish it off.

    You're jumping in the deep end of the pool on reloading.

    Ideally, you'd use the RCBS .44 AMP Case forming die set (RCBS part no 58367), but it's $303.95  :panic



    To do it on a shoestring, I guess I'd rough cut the cases with a small copper pipe cutter:



    After that, get these for the final trim:

    http://www.midwayusa.com/viewProduct/?productNumber=576407
    http://www.midwayusa.com/viewProduct/?productNumber=271467

    Then maybe run them through the sizing die.

    And then one of these to read the inside of the case:

    I make no guarantees about how well all that ^ is going to work  :shrug

    For calipers, get a steel 6" digital or dial caliper.

    Thanks guys! Yeah, jumping in the deep end. But Black Sunshine is going to be ready soon (or so I was promised). And if I want to shoot it I need ammo. And it's clear I need to make my own.

    I knew what I was getting into so now I just gotta suck it up. ;D

    The tubing cutter will work, but getting a nice straight cut on .308 brass is more difficult than copper tubing.  If you go this route, buy a good tubing cutter.  I've actually used the tubing cutter/Lee lock stud trimming method,it works, but it encouraged me to find a better method in short order.

    Looks like the guys have steered you in the right direction, so I'll add only these-

    1.  Patience.  Take the time to do it right.

    2.  Measure twice, cut once.
    This may be considered as the true palladium of liberty. . . . The right of self defence is the first law of nature: in most governments it has been the study of rulers to confine this right within the narrowest limits possible. Wherever standing armies are kept up, and the right of the people to keep and bear arms is, under any colour or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction- St. George Tucker, Blackstone's Commentaries

    Trust me, I'm all about quality over speed. Each round whether it's for practice or defense I'm taking my time with. That and it wouldn't suit me well if I let someone shoot my carbine and have it malf due to a crap round that I made.
