Shootall,
Yes, the 7mm (being I think .280 caliber) is slimmer than the .308, . . by 28/1,000ths of an inch. Far too little for me to care about. A random headwind, or a 10 or 15 yard range difference, will have more effect on the terminal ballistics than that small measurement. Give me the 180 grain bullet of the .308 any day of the week on an Elk.
OK, but I can agree with you on one thing. I live in Virginia too, and the 7mm-08 is absolutely perfect for any deer we may ever find here.
Best Regards, Mannyrock
