Go pick up a box of Winchester longbeards in #5 and see what ya think. I was amazed at the difference it made in my gun. Even misjudged distance on a bird out in a 640 acre open mud field lol. I was putting a stalk on him behind the tail fan of one I killed the day before. Knocked him down at what I though was around 40 yrds ended up being 63.
Or if ya really want "wow" factor look at those TSS loads lol. 10 bucks a round but folks are putting 300+ in a 10" circle at 40 yrds
