I have been trying to get one of Ed Harris’ .312″ 160 gr moulds like he originally designed for NEI, and that was later done by Lee, but without the changes Lee made to it. Jarod Todd at Heavy Metal Molds (HM2) did a run of about 60 of the original Harris design molds back in 2013, but apparently is no longer making these.
These molds were designed specifically for the 7.62x39mm CIP cartridge with its short .239″ case neck length, but also worked well in a number of other 30 caliber cartridges like the .308 Win and 30-06. This was one of the few designs made specifically for the 7.62×39 rifles, such as the CZ 527, SKS, AK, etc. To see more about the specifics of the design, go to: http://castboolits.gunloads.com/showthread.php?206520-HM2-30-31-cal-160gr-6-CAV-Ed-Harris-Design
I started an Interest Thread on the CastBoolit Forum early last summer to do a rerun of this mould. Its picking up some interest now. To see that thread, go to: http://castboolits.gunloads.com/showthread.php?243393-Rerun-of-HM2-312-quot-160-gr-Ed-Harris-designed-mould
I started another Interest Thread on the CBA Forum at the same time. To see that thread, go to: http://www.castbulletassoc.org/forum/view_topic.php?id=10762&forum_id=105
Since this was an Ed Harris design, I contacted Ed asking his permission to do another run of this mould. Ed gave his approval.
These moulds could probably be made in other diameters, such as .310″, .316″, and .325″ like they were the last time so they could be used in anything from the 300 Blackout to the various 8mm’s. Is anyone else interested in getting one of these moulds.

I would if we could get it without the crimp groove. Leave it like it is, just fill in the groove.
I think Tomme has raised a good point. For me the crimp groove is unnecessary. In fact, I hope to be able to seat this bullet with the gas check right at the bottom of the .239″ case neck of the 7.62x39mm case, which would put the case mouth on the top driving band. If I crimp the bullet at all, I would use a Redding taper crimp die, and not do a roll crimp at all.
I think, if anything, eliminating the crimping groove and tapering that section from the .312″ driving band to the .306″ nose section would increase the total bearing surface and make it better in terms of accuracy and velocity potential. I think eliminating the crimping groove would also make this bullet more adaptable to other cartridges besides the 7.62×39.
I wouldn’t object to removing the crimping groove. What do the rest of you think?

It is a redundant feature from my needs.
I suspect that it was needed for use in semi autos.
I want to use this bullet design in all my 7.62×39 semi-autos, but I don’t use roll crimps on those. Actually, I’ve never used roll crimps on any of my jacketed bullet loads in those either. I only use the Redding taper crimp die I mentioned in my last post. The Redding taper crimp die does a fine job of holding the bullet in place, and doesn’t unnecessarily damage it.

Here’s a link to another recent thread on CastBoolits Forum that shows how well the Ed Harris’ HM2 .312″ 160 gr mold works in a .308 Winchester rifle. http://castboolits.gunloads.com/showthread.php?260120-HV-308-test

Something to look at
This is the Ed Harris design
I would say if we are going to call it the Ed Harris design this is what we should make.
Any changes should be a new thread.And just as a note:
From the crimp groove to the meplate is identical to our 311 155Gr. bullet (fits the throat the same)
Ours holds a little more lube but is not much different.

And we have it in stock.Bullet maker, maker
