I finally got the bedded Omega grouping well and out to some distance.
I'm shooting the 200gr T/C Shockwave over 110 gr of 777 FFg powder. Gun was modified by fully floating the barrel, installing aluminum pillars, and bedding. This tightened up 100yd groups to about .75".
I zeroed at 200 yards, giving me about 19-20" drop at 300 yards with groups of 2-3" at 300. I calibrated my Leatherwood In-liner scope at these distances. It shoots too flat to calibrate 100-300 as they suggest, so I wanted to try 200-400 instead.
There was a 5-10 mph variable wind blowing as I moved out to 400 yards. I don't know what kind of drop I was getting, except that it was 10" more than what the cam on the scope elevated for. So I was kind of disappointed in the scope. The groups were decent in terms of vertical spread (3-4"), but the horizontal spread due to the wind was worse (8"). Total drift at that distance was 2-2.5 feet.
Not that the bullets have much energy at that range (400-500 ft-lb) but the drift and wind-induced spreading worried me in terms of shooting large game. Maybe with practice I could do better as I wasn't even trying to compensate for anything, but 8" horizontal off the bench translates into bad shooting in the field.
It was really neat reaching out to that far of a target with a ML though. It takes nearly a second for the bullet to reach the target at ML velocities (MV 2215 fps, 400 yd velocity just over 1000). Next time I'm set up to shoot high power at 500 I'll have to try the ML too...but I KNOW my scope doesn't have the adjustment for that kind of drop as most of it is taken up from the barrel contour.
