I bought two boxes of #2's one 3" and one 3.5" and went to the patterning board with them I put them up against Federal Black Cloud, Federal Premium, Remington Nitro Mag, Winchester Supreme Vs some old patterns with Kent.
I put them through a Wingmaster LC barrel and a SBE II using a combo of Trulock, Carlsons and Factory chokes.
This is what I found looking for the best factory 3" steel #2.
#1. Remington, Very good quality components, patterned very tight.
#2. Federal, Tie between the Premium and BC, but I chose the Prem. for the higher pellet
count and no issues with the Flight Control wad.
#3. Winchester Supreme, Not on the same level as Fed. or Rem.
#4. Kent, Cheaper quality components did not pattern nearly as well as the others.
#5. Hevi-Metal, By far the worst patterns of all shells tested no consistancy to the patterns with any choke tested, Crimp is open and not sealed at all. Waterproofing = 0
I called Environ Metals and talked to some folks there they were very nice! and they sent a new box for me to try from another lot but I had the same result, every wad either hit the patterning board or passed it (@40Yrd) and when recovered they had shot still stuck in them, If they change the wad they might be on to something but right now they are a waste of money I will not take take them to the blind and risk crippling birds with them.
