I made some 357 magnum 158gr with Herco recently. I found some 110gr (I forgot I had) and wondering if anyone has load data for that using Herco?

Possible Downtime Alert
I am working to migrate THR from the current cluster to a new one. I would like to get this done before the weekend, but it's unclear what the timeframe will be, as testing is still ongoing. As I am writing this the new (rebuilt) host is doing a burn-in to ensure that everything will keep running under load.
When the migration happens users will see a Cloudflare message indicatating it cannot connect to the server. This is expected, and depending on how the migration goes this may last from 30 minutes to 3 hours - I won't know more until testing the various migration options is complete and I have finalized the plan.
More information is available in this thread.
As always, thanks so much for your patience.

This link shows older Alliant data that had Herco loads for bullets 110 and others on page 2.

Copied from another forum! (Cast Boolits) Use at your own peril:
Google: "Alliant, Herco, .357 magnum, load data"
Lyman 45th Edition Reloading Handbook and for the cast boolits it stated for HERCO powder:
121 gr. cast --- Min: 7.0 --- Max: 11.9 (compressed)
141 gr. cast---------- 7.0 ---------- 11.8 (compressed)
150 gr. cast --------- 7.0----------- 11.7 (compressed)
158 gr. cast --------- 7.0 ---------- 11.6 (compressed)
168 gr. cast ----------7.0----------- 10.0 (compressed) - my favorite 38/357 boolit
195 gr. cast --------- 6.0------------- 7.5 (compressed)
The authors of similar posts in the thread could not recommend loads over 10 grains for the 158 grain do to pressure signs and recoil impulse!
All the best,
