the different patches seem to do the trick. i shot five times using 75grs of rs, a hornady prb using the ticking for patches. my target was at 70 yards and i was leaning against my truck bed. first shot hit far to the right and low so i moved sight then i hit far to left moved it back alittle then aimed dead at center and high and thats where i hit ,aimed lower and bullseye next shotbullseye.
