I've had good luck with the 70 and 75 gr Berger VLD's, 69 gr SMK's ,and the best luck with 75 gr A-max's in my 8 twist 223. I use Lapua brass and 25 grains of Varget for the A-max's with a Win SR primer. Started this combo with Fed primers and got way tighter groups with the Winchesters. Good luck in your adventures and hope you find what you're after.
