Snap shots covered it all well.
I use both a 40g nos ball tip and a 50 grain. in a rem 700 22.250 All depends what I'm shooting at and where. 40 g. dissolves corvids, and stays inside geese and foxes at 100 plus yds, so reducing risk of ricochet. 50 will rip a fox open up to 300yds. 50 more stable in heavy wind. Lighter bullet and heavier load will tend to make bullet disintegrate, so far never heard a ricochet with the 40, no doubt it could happen one day, but have when using 50's. Backstop should be as big and sandy as possible, always scout the shooting area in daytime, look at the ground,
