currently my thunder stick likes 42.5 grains of IMR 4064, federal 210 match primers and topped with a 168 grain sierra match king. (Not sure how fast its going) If I substitute the 168 grain for a 155 grain and use the same amount of powder will the accuracy get better or worse. the barrel is 24" with a 1 in 12 twist.
What I am trying to do is use the lighter bullet with the same amount of powder to reach paper a bit further.
