It's just a .308 grandpa... No more 'deadly' than your fudd rifle...![]()
I just took the plunge into expensive scopes and put a Zeiss Conquest 4.5-14x56 on my M14. That will be fine for 400 meter shooting like you describe. I can't really imagine someone seriously hunting goats at 400 meters with open sights or aimpoints. I mean, forget for a second that it's a battle rifle and just look at your game and the range. I don't know anyone who goes goat/sheep hunting with iron sights/aimpoints with their long range bolt rifles, that's for sure...
You will love the Aimpoint on the gun.. I love my CompML3
I love that stock.
