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!

I’m interested in seeing where this goes. Might have some time this week to come up with some drawings to get the ideas rolling.
Interested to see what Mike has to say about this as far as how much bullet we can stuff in the case. He was on the ground floor of the 500 grain SP bullet and should have a lot of knowledge as to the limitations for this one.
Bullseye Baldee
Tonight I did a little redneck engineering and chopped the body section off of a 500 grain NOE bullet and added it to the existing 354 grain bullet. I cut it a hair too short and wound up with a total weight of 593 grains, but I think this is roughly the dimensions we’re looking at to get in the ballpark of 600 grains.
I am not a bullet designer and this is not an NOE drawing, simply my own modification of an existing design drawing. Excuse my MS paint modifications but a visual representation tends to help get ideas flowing. I have not altered the original nose profile of the 354 grain bullet or removed the crimp groove, that can be done by the professionals.
**Paging cornmastah…**
It looks like we’re approaching roughly .875 -.925″ inside of the case depending on your seating depth, I seat the 354 grain bullet with the case mouth a good ways short of the crimp groove. Of course this is all subject to change if we modify the nose profile as it could have more room before touching the lands. Compared to the original 500 grain bullet with a body length of .725″ this should put about an additional .15 – .2″ inside the case.
I have no knowledge of projectile length and the affect it has on stabilization… The only comparison I have is that 220 grain match kings tumble in my 7.5″ 300 blackout barrel with 1:8 twist, but the 247 grain NOE bullets shoot just fine. I’m interested to hear input from others with more knowledge on this subject as my 458 barrel is a 10.5″ with 1:14 twist.
Let’s get this hornets nest stirred up!
The more I look at that the more I like it. I think I would like to keep the .250 nose. I feel when running the flat nose pin the wide nose will be more effective. At that point all we would need to do is slap the 354 nose on the 500 grain body then add some length to get our desired weight. Again good work man!
