A buddy of mine used the 3rd degree. I was pretty sure they were a marketing hype and advised against it. Tell ya what out of his gun they were fantastic.
Longbeards imo aren’t great loads. Way too tight a pattern w most combos. Actually haven’t seen any that wasn’t but yesterday I mounted a scope on a gun. After a few shots to sight in I had some longbeards lying around so I shot em and w a scope I guess it was precise enough for my aging/compromised eyes that I’d feel comfortable in that gun even at close range.
I believe the halo/pattern in the 3rd degree was much friendlier though.
