Michael,
Thank you for the teaching!!! And thanks for reinforcing positively the idea I had for my next long range shooting-hunting rifle. Another reason for me to consider the 308, is that I dont live in USA, and finding cases, primers, bullets, powder is very difficult, except for the 308, because it is the cartridge the military and law enforcement agencies use, and you can get ammo from them. So planning for shooting a lot in my particular case the 308 fits just perfectly, and it will also be my teaching caliber for long range shooting. I know I will be able to shoot with it more accurately farther out than with my 270 Win.
Thanks again for the class!!!
