Personally I wouldnt use barnes to shoot rabbits and neither would a lot of hunters and PH's I know.
I've shot buffalo with both 300 gn round nose solids and soft nose Woodleigh's and would recomend them to any hunter,hunting dangerous game
I have what is left of a barnes bullet retrieved from a large feral pig and all that was left was the copper jacket.
Not what you want for dangerous game.

Remember iff you pay peanuts all you will get is monkey's.

I've also used Woodleigh's in the following calibres:-
303,333J,416,470,500J ,577Ne.
Never ever had a problem with bullet failure.
