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
