any load suggestions for the 70 grain bullet? thanks for the reply

[pdog2062]

without listing exact loads usually what works best for me is the same load that I use for 55 grain bullets in my 223.the varget load is slightly compressed.sending a pm

They are one in the same.
I built mine in 2011 & have over 210 coyote and 4 antelope taken w/it.
Coyote loads are with the 58 & 65g vmax in front of exterminator powder & these will drop em at 600 yards with no problem.
My antelope load is the 80g ttsx line & 95g nosler HBT bullet in front of H335.
Accurate as heck & I have no issues shooting past 800 yards when I need to as long as the winds are not 30 mph out here.
