New Shop

Hey All,

As some of you know, my work has me all over and for the last couple of years, based away from the shop. Getting back to work on Heavy Metal stuff wasn’t as frequent as we needed. I finally moved part of the shop closer to the work base and now (even tho I still travel most of the time) I can spend much more time at the new shop. We are still getting machines set up and leveled out, but we are making progress and parts.

Next thing we need to add is a customer order / build sheet that you can fill out and send in. That way it won’t take 10 emails to get things started and we will have an order number and queue system to work off of. I would like to have it updated in real time for tracking, but we’ll see how it goes.

The old shop phone number: 231-233-0839

Don’t call it, I’m not there. We are working on a new number for the new shop.

Thanks for hanging in there with us.


357’s Come to the AR!

We literally pulled the trigger on our new 357 AR’s. The 357 AMag (357 Magnum Rimless) and the 357 Amax (357 Maximum Rimless

357a Cases are formed from a multi step process from 5.56 brass for both the 357 AMax and 357 AMag.

We did a pistol for the AMag

357d with a 10″ barrel and pistol port gas system.

For the AMax, we went with a carbine barrel and gas system.

357x We are working on load data so stay tuned!

1/2/18: New for 2018 is BRASS! Starline got us some “blank” 556 virgin brass that has not been necked down. Now all we have to do is trim, prep, and load! Thank you Starline!!!!!!


Dies & Reamers

Have you ever needed a custom die or reamer, or tired of waiting 3 – 6 months for that new set? Heavy Metal has made a few of its own custom chamber reamers and die sets and we are going after improving this set up for you. I have a set of custom reamers that I have been waiting for over 6 months now and enough is enough. The drawings were already completed so we took matters into our own hands and turned out a set of chamber and sizing reamers.  From that set of reamers we made the custom sizing and seating dies. Now it’s time to reload!

22 Caliber AR’s

We just finished our new 22 TCM carbine upper! This is a gas or DI gun running an adjustable gas block in the pistol port location. Test rounds are with 11gr of H110 under a Speer 40 gr Varminter bullet. Quick Load predicts about 2350 fps from a 16″ barrel for this mild load so we’ll post more development as we get further down the road.  The 22 TCM now gives us another 22 caliber round to go with the 22 Reeds Express and the 22 UZ.

Update: 3/15/16: We ran two loads for the new 22 TCM and I am happy to report we have a 3000 fps round on our hands! Using 12gr on Lil Gun and 12.5 gr of H110 we hit over 3000 fps on the chronograph using the 40 gr Speer Varmint bullet. Those lighter bullets should pick us up a few more but 3000 ain’t bad. Our next move is to run some 62gr SS109 bulk bullets out of M1 Carbine mags and see how they do. The 22 Reeds Express handles them fine so I expect the TCM to do the same.

Uppers are in stock and ready to go!
