Re: .264 Win Mag Long range load?
Glad to see I am not the only one shooting this rig. I own a Sendero as well, and I love this caliber in this rifle. I use 140 Berger VLD's @3200fps. This combination hits like Thor's hammer. As far as accuracy goes, at 100yds. its a jagged 1 hole group on paper. I zero at 200 yds with my scope and it will shoot .5-.75 moa all day long. After having done that, I was off to the steel plates and silhouettes. Shooting at 550 meters at our range, it will put them right where I aim with this load.
Give the Berger's a try, you will not be disappointed.
As far as finding load data for the 264 Win. Mag. Its a little on the scarce side as you probably all ready know.
