However, she can't force a 7mm-08 to magically produce more energy.
Not magically,but by simply installing a longer barrel on the rifle,she can have it produce more energy with the same cartridge.
I don't know why your getting all worked up about barrel length. When did that enter the discussion?
I introduced barrel length after you made the totally idiotic statement below.
You can't make a cartridge have more energy.
But apparently you still don't comprehend how that is possible,even though I explained it to you.
In fact you are probably naive enough to believe thatall 308rifles actually produce the velocities listed on the federal and Hornady werb sites.Even ifthe barrel is the same length as listed in the tables,the velocities produced byfactory rifles are usually less than those listed in the tables.The reason for this is that most test barrels used to test loads,have chambers cut to minimum specifications which results in higher chamber pressures and more velocity than is produced in factory barrels.
