Just sighted in my friends Omega this weekend. Use 90 grains of T7 and a 240 rain xtp in the supplied sabot. I mounted the QR leo[olds for him , bore sighted and be bullseyed first shot a 50 yeards. We will work this weekend on 100 and beyond. I would look at the sights forst male sure they are tight, look at the stock screwssecond. It just sounds as though something is moving around. When you set yuor stock screws next time, mark wear they set. You have a tight point everytime, not guessing what is and isn't tight.
