angrysoldier, you are using the right ammo for what you are doing. you don't want to be shooting 556 much past 300,you want that stuff going sideways the minute it hits your target. use your 338 LOTS and keep us safe. Thanks for your service.
How the hell do you guys see a gopher sized target at 600 yards anyway?!! That's a loooooong way for a 4X6 card sized target.......
Having said that I'd still go .223
ive shot 556 out to 600 meters and past 300 you cannot trust it not to tumble. the other cal im not sure about it. but ive fired many thousands of 556 and i dont trust it past 300 meters.
i work out of the infantry school in gagetown. our rifle are about halfway through their bores. as i said we dont trust them past 300 meters. 400 -500 on a good day.
You guys are seeing tumbles on a c-7 with ivi past 300m? How are your bores?...
Not surprising. With the amount of cleaning and beating battle school rifles see, I'd say if IVI is tumbling past 300m, those bores are done. Still great for training, but I wouldn't send them to CFSAC.
