Reliable source for 700 grain loads for .500 S&W?

[The German]

Does anybody have a reliable source for load data for the 700 grain LFN bullets for the .500 S&W Mag.? I found the 24-25 grains of H110, but that is just internet forum information not coming from a powder or bullet manufacturer with pressure data.

That for handgun or long gun?

Looks like ouch, no matter the platform

Underwood loads that bullet to 1200 fps. I have a Contender barrel chambered to .50-70, and occasionally use 750 grain BMG bullets loaded to 950 fps. Lighter than the big revolver, recoil in the T/C is….impressive.

I’m not sure I would trust these data, but you never know: https://ultimatereloader.com/2020/11/12/most-extreme-handgun-bullet-500-sw-magnum-700gr-hammer/

Loaded up some 700 gr bullets for the 500!

Working up a load for some 700 grain (.1 lbs each) bullets for my S&W 500. The first time out, I loaded about as low as I could. Not the body beater I expected. Tonight, I loaded up three more loads working up to max. Now I just need to get out to test them. I did have one problem. The...

500 S&W magnum-700 grain cast

I GOT MINE! This is a group buy from over on castboolits.com. It comes from Miha Prevec who lives and works in Slovenija. If you've never seen one of his molds, you're missing how nice they look. That's if you don't mind waiting for over a year, it started on 01-19-2010! What a fine piece...

Thanks - I found the data on reloadammo, but was hoping to find some data provided by manufacturers or somebody who did actual pressure tests. Looks like I will have to go down the "trust the internet and try" path... Will start with 23 grain H11 and chrono my way up - looks like the max to expect is 1200 fps, out of my 6.5" barrel most likely get 1100 or so.

This Bill from Ballistic Supply. We manufactured the 700 gr. Back in 2004. Ranger Rick cast the slugs for us and our standard loading was 25.0 of H-110. Pressure from Hodgdon check for us was 42,000 map(psi). I had them also run CFE Blk Out @ 34.0 grs. and it was about the same. We are shooting 33.0 of the Blk Out and it is great, 34.0 is starting to compress so consider it max. Hope this helps, hang on tight !

Thanks a bunch everybody! I loaded some rounds with 24.0 H110 and test fired them - that's more than enough for me
Great to know the detail that Bill provided!! Thanks Wildbilly!!
