I am a real amateur and still learning about wheel guns and shooting and ammo, so please excuse a noob, and thanks for your patience.

I am interested in this discussion as I own a 13-1, which if I read other posts is nearly identical to the 19. I also read the other discussions about the potential for my 13-1 forcing cone cracking. After reading those posts I stopped carrying and shooting my 13-1. I understand to a very limited degree the explanation, but I still have questions.

I have a bunch of 125 gr, some 158 gr, and some 110 gr, all either SP or HP, and they look to be all the same overall length, within a whisker. Even the same bullet from different manufacturers are the same length. The only difference then is the bullet weight and fps.

I took some factory data from an internet retail site just to use as an example, and I understand fps is not psi. The Remington rounds (I have several boxes of each, alone with a bunch of the Winchester) look very close in velocity - 1220 fps to 1450 fps. Is the 1450 too high for my 13-1? The 1600 fps for the DoubleTap is higher, is it THAT so much higher that it shouldn't be used in my 13-1? I have a box of these, too. Most retailers don't list the psi ratings of each bullet but the fps is easy to find. Are any of these listed below the "hot loads" and should not be used in my 13-1?

I guess I am asking, what is the line I shouldn't cross, not knowing the psi values for every type and brand of bullet, to protect the life of my forcing cone?

Again, thanks for any info and thanks for your patience.
