I've been thru your same process for quite a while. The luckygunner tests convinced me that it's hard to find bullets that will expand reliably at 38 special velocities. The Hornady XTP bullets don't open up until you get to .357 magnum velocities. There are some factory loads that work well, but I don't know how to buy just the bullets for reloading. And nowadays it's hard to find any .38 special ammo of any kind, especially the good stuff.

What looks good to me are Hornady 140 gr FTX bullets. The problem with all hollow points is that the little cavity can get filled up with fabric or fur or something, then it works like a round nose bullet and won't open up unless it's going really fast. The FTX bullets have a plastic nose that gets pushed back into the hollow point cavity so they should open up no matter what they are hitting.These are easy to find out there on the internet and according to the luckygunner tests they seem to expand reliably. I bought some and will be trying them out.
I keep a CCI snake shot round handy in my .38/.357 speed strip just for the rattlesnake by the back porch scenario. Those things really work well. But for me the best anti snake weapon is a .22 rifle with a CCI snake shot round. Stand way back, hold the rifle like a pistol, put the muzzle right in his face, and pop him.
