I have been using predator hollow points for years to eliminate rats using an old .177 discovery. I recently picked up a couple of tins of rifle premium series 8.33 grn .177 Diablo style pellets. Color me impressed! I am still getting 930fps and they are accurate out of my disco out to 20 yards, I am getting about a .45" group at 20 yards. Not world-class but devastating on rats. The profile on these is much closer to a flat point than other "round nose" pellets I have used and they wack the critters with authority, generally not exiting on the far side with body shots. I need to get a few pictures but at a lower cost, and better accuracy, I think I have found my new favorite pest removal pellet. What are your experiences with round nose vs hollowpoint on pests?
