Picked up my Remington Sendero 7mm STW a couple years ago. I'm shooting a 140 grain Barnes TTSX, loaded with 84 grains of H1000.
Took this buck in Western Oklahoma at 558 yards.
Got this one on the same ranch last season at 304 yards.
And took this does last season on my family's farm at 644 yards. Yea, it's a little thing but my longest shot on game so far.
