Hey, guys, new to this forum. I have a Thompson Center Omega .50 cal. which I plan on using 150 gr. 777 pellets and a 250 gr. Shockwave bullet. My biggest problem is that I have only 50-60 yds. on my property that I can use for sighting in my gun. Is there a formula that can be used to predict approximately where my bullets will hit at 100 yds. or more if sighted in at 50 yds. with this bullet/powder combo? A friend of mine said that 2-3 in. high at 50 yds. would still be dead on at 150 yds.(??)
