My 190 gr VLD's wouldn't shoot worth a ****. Inch and a half at 100. I seated them at the max my magazine would handle. Two different powders, RL-25 and Retumbo. Charges starting in the mild range. This being in a Remington 700 .300 Ultra, 26 inch barrel. Do I need to seat further out? I measured my chamber with Stoney Point tools, but if I seat out close to the lands, the OAL seems extreme. Help. mtmuley
