I'm looking for all the 357 Herret loading info you may have gained through experience. Thanks folks. roger

It's been several years since I had my 10" t/c 357 Herrett, but it was a good round. I was able to get just shy of 2000 fps with a 200 gr cast bullet using AA 1680. If you can get any Winchester 680, it is the powder to use. I tried RL-7, but it is too slow burning.

I have had very good results with h4227 and hornady 180 ssp bullet.
