The 40 grain Sierra h p is a tough bullet, probably too much for a hornet. The Sierra 40 grain hornet sp is a good hornet bullet over around 13 grains of Lil Gun. If you want to add some fun factor to the hornet try some Calhoon 30 grain hollow points over H110, gives a whole different perspective to the 22 Hornet. they will do a little over 3400 and wreck a praire dogs day.
