I am using a Pure Gold .670 with hevi straight 7s. It has killed past 40, but throws a great pattern from 30 to 40. I am not in the long range sniper crowd.
My xxffull that came with my 535 has best pattern I've seen with my gun at the 40 yd range. I tried the Indian creek and has an ok pattern at 60 yds but not like the factory xx at 40 yds.
