"Serious" can have totally different meanings to different people. When I was doing my squirrel hunting I considered myself somewhat Serious.
I used ordinary .22 LR standard velocity Solid Points. I never found them lacking in either killing power or practical accuracy.

Serious to me was bringing in the number of squirrels I killed with the least expenditure of shots fired. If I do say so myself I ran a very good average of the ratio of shots per squirrel.
