You are a better shot than me. Too much LR shooting prone off a bipod not enough real world practice. As for moving I can't hit a flying barn with a shotgun so movers are a non starter for me.The Eland was the most difficult & most challenging...... It was on the move at 300 yards. Took 3 shots. I know that sounds like a bulls#i+ story.... But it's true. My PH's were @AAA Africa Serapa Safaris & @Hartzview Hunting Safaris, they can attest. Had it been still, with it well placed in the boiler room. 1 would have done the trick.
Nice to know the 168ttsx is up to the task
