I mostly shoot rainier 140gr bullets out of my 4" model 15. I loaded up a few 125gr hornady xtp just to see how they shot and they seemed to shoot quite nicely. Do you think these bullets will expand at 38 spl velocities? (I am getting 914 fps on the chrony)

I think the 135 speer would be a better choice for expansion, but I can't seem to find any in stock anywhere.

I am looking for a farm carry load. Groundhogs and Coyote being the targets.
