RE: Ive Got Bad Problems With My .300 WBY
WOW!!!!! Stupid question but are you using the exact same rest and shooting position when shooting from the different distances? You already claim your range only goes to 200yds. Does this mean you are taking these 300 yd shots at another location using a different benchrest setup. Little things like a carrying sling catching the sand bags can drastically affect a shot. Also have you double checked mounting screws? I would definitely try another load before winging it into a lake!
