Want to start loading some 357 amp, but haveing a hard time finding reloading data. I know I've seen some other post but cant seem to find them. Want to start with some Sierra sports master 158gr JHC. Need data using Win 296 or H-110. After that will try some 160gr, then some lighter stuff. Thanks in advance. Any and all help appreciated!!!!!

Larry,
When you get around to testing the lighter bullets, here's a couple of moderate loads that have tested fairly well and are very accurate and function superbly in my 6.5" EL Monte:
OAL 1.6"
23.5g H110, 140g XTP, CCI 350, Starline 44AM cases sized to 357AM, 1768fps.
22.5g H110, 140g XTP, CCI 350, "processed" '64 WRA 30/06 cases to 357AM, 1737fps.
The WRA cases, run a little heavior=less case capacity=less powder/equivalant load- can be used as an out in the field throw away seeing as Starline has new uniform brass. This load is surprizingly leathal (2 whitetails 50-60yd shots, both ran maybe 35yds and dropped, excellent expansion and complete penetration on broadside and quartering angles, woodchucks hate getting stomped by this load).
Paul V.

I bought some 158 gr GCHP from Rim Rock bullets in MT. They came today and look excellent.
Thinking of trying them in my 357 AMP using 2400 since I have had the best luck with it with cast bullets.
I almost have my chrono/laptop figured out. Hope to post some bullet/velocty combos before the snow flies.

Well loaded 10 rounds with 21.5gr Win 296, and speer 158gr jhp. Shot great. will load about 50 more to see how it all goes. Waiting for my buddy to find his crono so we can see what they are running. will follow up once he finds it.
