I remember us discussing this over on the Colt forum.
Once in a blue moon I'll have a cartridge feel a little sticky (meaning a spent case won't just fall out, it will need a tad of force before it "pops" out). But most of the time it's fine.
I decided the other day not to go above 14.5 with the Python as I had reached my desired velocity (1300+). But I sure don't want to beat up a fine gun such as that. I would die if I damaged the Python.
I always shot 15 grs. of 2400, 158 gr. bullet, 1400+fps. I gave it to my son and that is the load he shoots. Larry
