FWIW, I find a load of 7.7gr. tends to be a nice accurate load, without leading, and I'm guessing it's running around 825-850fps.
I read somewhere that the newer 629's tend to have tight throats, and mine measure out at .4285. Since the Hornady's are .430 to start with, I wonder what effect there is in having them sized down in the throat, only to be pushed up again when they hit the bore? Maybe that's a reason for them not reaching the published vel? Guess I could have my throats reamed out a bit, but I'll keep that idea for a later date, after I throw more down the tube.
ps: if anyone out there has more PB data to share, I'd be very grateful.

I don't know what published data you're refering to but most
published data is from test barrels and lists velocities that
are far higher than handloaders will achieve in their guns.
Also swaged bullets will usually run a bit slower than cast
bullets with the same powder charge. I've tried PB powder
in handloads with different ctgs and found it to be a very
mediocre powder, very position sensitive with large velocity
variations. If you've found a load you like with it I suggest
you use it up and don't look back, it is gone.
