I have tried many bullets through my T/C Omega 50 Cal. but I can you this. These 250 gr. bullets are the ticket. I was simply amzed at the grouping that I got at 100 yds. I used 100 gr. of 777 pellets and I can tell you that the holes were touching at 100 yds. I moved back to 150 and the drop was around 1". Plus, they expand like you wouldn't believe and they go down the barrel easy. They may not be as good in other guns, but in mine they were simply amazing. I will be using these this weekend for sure.
