80gr or 75 amax

[foreign]

i cant decide it i want the 80s of 75 in the 223. aiming to hit bunnies at 600 and further if i can manage it. 24inch barrel with silencer.
will the speed added in the 75s make up for the lower bc?
thanks

What twist is your rifle? That's the main factor. I'd run the 80's if you have a 1-8 twist. There pretty close to even at 600 yards.. but...out to 1k the 80gr seems to work better for me. And the 75gr'er would run better with the 1-8 as well.
Remember, if your going to push the round hard the suppressor will add a little back pressure to your over all peak pressure.
Good luck.
