I would use 148 gr WC's in my J frames, and J frame Centennials are all I have, except for two reasons.
One is most J frames with fixed sights shoot quite high with the slow heavy ammo, and the other reason is that I can't practice with them at the local indoor ranges. Have to have plated ammo. And, at my age, those are my only options.
I use Federal 130 gr HST plus P in both revolvers. This ammo gets good results in jello, has less recoil than the Speer 135 gr SB short barrel, for what ever reason, and is a nice WC profile if it doesn't expand. Regular HP's are just round nose if they don't open up. And, the HST shoots close to point of aim in both of my revolvers.
I wish I could use target WC's. They are a cheap way to practice what you shoot, if reloaded.
I carry the Speer for a reload, since the WC profile of the Federal are slow to stuff in the chambers, probably especially so under extreme circumstances.

Best,
Rick
