I have been planning on using longbeard XR 5s. These patterned decent for me with 135 pellets in 10 inch circle at 40 yards. Picked up a box of the hevi mag blends for shits and giggles. All I have to say is wow....173 pellets at 40 yards. I thought maybe weather changed shot pattern so I tried the Longbeards again and got 140. On top of that...the hevis have more shot outside the circle as well which makes me think there is simply many more pellets in the mag blend than in the longbeards which makes sense since the longbeards are 1 and 3/4 ounces of #5 while the mag blend is 2 ounces of 5,6, and 7. I know they are sooo expensive but it looks like patterns at shorter and long distances will be better with the hevis do to simply many more pellets in each load. I'll do more testing this week to confirm.
