Please be careful when using the match bullets on critters... be aware of your backstop...
I use varmint bullets on critters because they are designed to expand and terminate the critters. Match bullets have superb accuracy but often do not expand well on critters... Match bullets will ricochet!... I shoot around cattle all the time and have to be selective in the shots as well as the bullets. My exp. has been that groundhogs are some of the toughest varmints to kill.... crows are relatively easy cause the feathers act as a shield and aid in the expansion.
Good luck & have fun working up a load.
