The 308, 7mm 08, and the 243 are shorter actions. The 270 will be longer action and thus heavier. I had a 308 BLR that my son has now and loved it. Very accurate. Had to clean with a snake so I wouldn't have to take the lever and bolt out. It has to be on the exact gear to close properly if you take it apart. A long time ago I had one in 3006. Wasn't that heavy, but longer than the shorter actions.
