I've got my FAC application in at the moment and have asked for a .308 as its a caliber I know like the back of my hand, having shot comfortably in excess of 10,000 rounds of it over the years at Bisley (target rifle) at all sorts of ranges from 300yds - 1000yds.
I've put down for "deer, AOLQ and for zeroing/practice" so my question is this;
In the event that I was using this for foxes with, say, a 90 grain load what would be the difference between a .308 90 grain cartridge and a .243 90 grain cartridge in terms of ballistics and energy?
So far as I can tell they are both 90 grain in weight and are fired from the same case length with the same powder load behind them, its just one of them is a larger diameter than the other? So therefore the muzzle energy and ballistics should be pretty similar, if not identical?
Maybe I'm missing something here but to me that makes sense.
Appreciate your thoughts!
