I’ve been casting the HTC .459 500 grain projectile for a 458 socom. I love heavy bullets and got to thinking…I would love a 4 pin set 600 grain(with the flat nose pin installed) hp mould for 458 socom. I think the heavy bullet would be amazing for expansion. I know most moulds have 3 pins included flat, short and long. I would like to see this mould with 4 pins. Flat, short, long and longer for a deep hp cavity. I would like to see a similar profile to the 500 grain bullet. I posted this on the 458 socom Facebook page and have 5 guys interested already. I will urge them to sign up here on this forum so they can get in line. Anyone here interested in this? I have a name picked out as well MOAB (mother of all bullets). Thanks!

No worries, now is the time to make the nose design more user friendly for those with tight tolerance chambers.

I ran out on my lunch break to find IMR 4198 so I could run my experiment again tonight and compare how much room is in the case. Sportsmans Warehouse is out of stock and PSA seems to be cutting back on their reloading supplies so I cant help there. The only extruded powder I have is Accurate 2015 and it’s a “short” kernel powder. Also I have only seen one or two instances of someone trying it in 458 socom so I think it’s not going to be of use.

Anything that allows more flexibility with seating depth is ok in my book.

Is it a cheaper possibility to just get pins for the flat tip and the deep hp?  I don’t care about the rest of the intermediate depth pins.

It looks like that would work well.  I was looking at the 500 SP and the diagram has the main body at 0.459″ and the step down @  0.457″ so this design is more along the lines of it and I have no issues with seated length with PC on it.

Not really, he just includes them all at no additional cost (more work for him, but more options for the user).

You can put me down for a mold if you haven’t already….when we get a final cost I’ll have to decide if I can swing the 4 cavity.  If I have to pick before then let me know.

I don’t mind the .455 band. Still looks nice to me.

Also, you are using pistol powder with the 500 grain bullet?

Yes….I am using a bolt gun, so all I need is the desired velocity….no worries about cycling an action…..and you get 100% burn.

Quick load is a very valuable tool to help get a starting point with unconventional combinations.

Interesting thanks for the reply. Now about the new design. I like it but what if we shaved the band down to say .450? Maybe even more as long as we dont gain to much length. Would that aid us even more for feeding? Then could almost act as a crimp line and be back to only needing one mould. Just a thought what do you guys think?

No, the leverguns need the crimp where it was originally.  The 458 socom can have more bullet out of the nose than the leverguns, but the leverguns can have more bullet inside the case.  If the nose is too long, then the leverguns can’t left the round and feed.

Ok I understand. So do we think the last design is the money shot? I think it looks great and will produce a beautiful bullet.

what are your guys’ thoughts on doing the non crimp groove like my latest drawing, and doing the crimp groove with the original drawing (without the extended .455 band)?

I love that idea. Slightly different for those that want both.
