I'm drawing a comparison of the original Harris/NEI design NEI 311 155 GC 52A to similar cast with NOE, Accurate Mold, Heavy Metal and Lee.
I reached out to Joe for some measurements for OAL, olgive to base an OAL on the NEI mold he bought on e bay, Not sure if he's following this thread yet. but if anyone else would happen to have the NEI 311 155 GC 52A I would appreciate some measurements from their mold. In Walt's catalog it looks like there is a small metplat and not a complete round nose. In Ed's picture it sure looks like its a round nose. Maybe there was more than one design? Thus the moniker "52A". Ed would know about that. I seriously doubt that there are two designes but you never can tell. I have the Lee and it does have a very small .0625 metplat.
One more quick question. Accurate Mold is a great group but as Ed said the smallest metplat they can provide is .187. Is that the smallest metplat that can be cut?
Here's what I have so far:
And this is the information I am looking for from the NEI
I'm doing this because I am curious. And I would be probably be better off just letting it pass. But the base design looks ideal for a number of diameters (.310, .312, .314) and multiple weights (155, 165, 185 (two lube groove) 200 (two lube groove). I would appreciate some comments on that last one. The last Autocad I worked with was 25 years ago and nothing is on my computer to draw it up properly. Thanks, Bill.
