Well I didnt get any pictures of the targets. The M80 ammo shot like crap to say the least. It could have been partly our fault but neither one of us could get it to group as good as we had liked.
Our first set up was at 100m just to confirm zero. We got it back on target just fine but it was shooting groups averaging about 1 3/4" or so. We didnt even bother measuring haha. Not trying to make excuses but after talking about it, there were alot of things working against us not counting possible shooter error. We were shooting MG ammo which is a far cry from the match ammo that its designed for. And as with most weapons in the Army's inventory, only God knows how many shots have been through it and how it has/has not been taken care of prior to us getting the rifle. So nothing really points to tight groups here.
As far as the coefficient, that really helped alot today. We plugged in that plus all the other info to include environmental factors and came up with a chart thanks to the Sierra software. It was pretty accurate as far as we could tell. Had a slight tail wind that wasnt figured into the chart but that didnt affect us much.
After the initial zero we backed up to approx 250m (as far as we could on this range) and were able to consistently hit silhouettes on rapid fire strings from various supported positions and timed fires. Me being a lefty it still sometimes feels akward to shoot a right hand bolt, especially with any speed. But its all good.
All in all it was a good day I suppose. Still didnt shoot as well as we wanted to but maybe they will get us some more M118 Match so we can put it to good use. If only we could use hand loads haha. Thanks again for the responses, maybe this info will help end the lives of some terrorists soon GI1
