I load 158 grain lead semi wadcutters over 5.8 gr of Unique for target shooting in 357. About 900-925 fps.....Accurate and easy recoil.Yes , and a welcome from western Pa. too.
I have a 4" Sp . One of the newer ones , .357 . I did swap springs , and "cleaned" up the insides some ....really made a difference. I also bought a different grip. Went with a Hogue wood , finger groove. That made a difference also. Good luck. Oh and BTW ...with full house .357s , its handful. I've been loading 125 gr XTPs to .38 sp. ++P loads. ( little over 1000 fps ) They handle very nicely , easier to shoot , and I think will still do the job if needed.
