Ok as a respite from the .600 OK I shot my 30-06 Heym double today. I tried a bunch of loads, but at 50 yrds all crossed! I am a lefty and the gun has alot of cast-off( as it has a rt hand monte carlo), but with the scope all shots crossed at 50 yrds this included the 180 gr Remington factory ammo the gun was supposedely regulated with.. Groups were good at 1.8 inches to no more than 2.0 inches but all still crossed. I didn't try it without the scope and don't know if the gun was regulated with a scope or not!My best load was 55 grs of IMR 4831 and a Nosler 180 gr BT(probably only a 2600fps load). From these results, I asume I have to drop the velocity , am I right?-Rob

Rob, If the rifle is crossing the speed is too High! The bullets are exiting the barrels too soon. You didn't say if this rifle is a S/S, or O/U, but both will cross if the speed is too high. With a S/S, the composite group will usually be a little low, but the same horizonally if crossing. With an O/U, the group will be higher for the bottom barrel, and lower for the top barrel, but but both will usually be high above the POA, but in line for windage! As someone suggested, take the scope off, and try it again. If they still cross, and I suspect they will, slow it down slightly, and try it again. Much American made ammo, for Europe, is hotter, than the ammo made for this country!
