Advisability of warm loads in J-Frames
This is not a recommendation, just an observation.
In 1967, I bought an S&W Chief's Special from a retiring deputy sheriff. Over the next 15 years, I probably fired a thousand rounds of warm handloads, plus a lot of standard factory loads through it. It went away in a divorce, still shooting well, and yet protects my former wife's home.

The warm handloads were a then-standard load, from an old Lyman manual: 158 to 162 gr. LSWC or LRN with 5.0 gr. Unique.
Later on, I got a Model 37 Airweight Chief and shot it loose with the same loads. It was my Always Gun for years, and I practiced regularly with it. Carried Win or Rem 158 LSWCHP+P factory loads in it. It got loose, and went to a S&W trained 'smith for a rebuild. Back to the same routine. (Not a fast learner, I.)
After the next end-shake removal, the gunsmith warned me I'd ruin the gun if I didn't change my stoopid ways. Now, it gets fired only with light loads, though still carried with the 158 +Ps. Remember, this is with an alloy-frame revolver, NOT the full-weight from the 1960s.
The cautions given above by
Mike & Mike are quite valid. Besides, it just isn't
FUN to shoot heavy-recoil loads in ANY J-frame. Practice with light loads, shoot a few +P occasionally, and your model 60 will last your lifetime and probably your heirs' as well.
Best,
