I shot 69’s all the way back on xtc matches. At 600 with 69’s better be good at wind calls. Also they shed velocity pretty quick. I shot plenty of 75 Hornady’s bthp at 600yds I been able to shoot clean a time or two. As stick says the 75 eld m is good one as well anymore that’s what I use for the 600yd line, I use N540. I used the 80 eld m at a 1000 (Brian Litz tested the bc on the 80gr eld-m bullet and it has a bc .505) Right now powder valley has 75gr hornady bthp priced right.
