Nice story and great job on that bull! There is a lot of info out there comparing a 30-30 with a .357 out of a rifle. The longer barrel sure wakes up the 357 and 45 Colt. Putting it in the right spot, like you did, and they will do the job.
Regarding a peep sight on a Rossi 92. Skinner makes a bolt peep that replaces the saftey lever on top of the bolt. I have one on mine and it works well, although I did have to install a taller front sight. Mine is in 45 Colt and I shoot 300 gr Deep Curls at a bit over 1400 fps.
