It took me a couple years to find the right bullet for the 243 Win.....Sierra 85gr. HPBT GameKings was my goto bullets when I did deer crop damage shooting.....shot 80-100 deer a year never lost a deer some would do a 50 yard death run....

I know several people that do deer control shooting and will only use Sierra 85gr. HPBT GameKings

Back in the 80's it was a MatchKing bullet when I started using it....name was changed to GameKing maybe around 1990...I'am going on memory so might not be correct....
