ok i found a load in my Lyman #43 for a 125gr castboolit 2.5gr of bullseye
800fps and 4.7gr at 1125 does this look right to you.in my 49 Edition it shows
now this is for a 125gr jacked bullet 6.5gr of Bullseye to start at 846fps /8.6gr
at 1315 fps which to use ?

Use midrange jacketed data for the Berry's plated bullets. That's the advice they give in FAQ section of their website. With some of their bullets I use full power jacketed data and it has worked well, but for starters, I'd suggest the midrange jacketed data and work up, if desired.

Hope this helps.

If you're solely interested in punching paper, I'd try 5.0-5.9 grains of Bullseye in 357 cases. This should give you somewhere between 770 fps at the lower end and 1050 fps at the higher end, depending on barrel length, cylinder gap etc. HOWEVER, velocities are very idiosynchratic in revolvers, there was an excellent article illustrating this called "Why ballisticians get gray" that appeared in the Speer Number 9 or number 10 manual. Since you are interested in punching paper, not people, I'd start low and work up until I found the best groups.

The load from the older Lyman Manual seems as though it is for a 38 Special, not 357 cases, Lyman lists 3.2-4.4 grains BE in their number 47 manual for a 125 jhp 38 Special and 6.5 to 8.0 grains in 357 for the same bullet. Those are magnum loads.

Using lead data for a plated .357 load is asking for a stuck bullet. (yes, it happened to me).
I would use the jacketed data and stay below 1100 fps.
