Whether you like the performance of this wad or not will be determined by your reloader and how it is set up. If your wad ram or shot drop tube is set to compress the wad, the wad will compress, but not spring back. That will cause problems.
Since you are reloading STS hulls, why not just use DRM's Fig-8 or Windjammer clone. Both are absolutely superb in STS hulls and there are NO fit problems. They both pattern beautifully.
This wad is my primary wad for my handicap shells. I do use 5lbs. of wad pressure to seat the powder and eliminate any air. Why? I don't know, I just do and it has worked for me for many years. Another plus to this wad is the fact that it works very well in Federal Top Gun hulls as well. I know there are those of you that will say it's a tapered wad and not suitable for Federal hulls, but, I'm here to tell you they work great in them as well. Don't believe me? Contact Kevin at Downrange and get his opinion.. Just my experience... Dan Thome (Trap2)
perazzidb81 a lot of people on this site swear that you cannot shoot that good with reclaimed lead shot. It must have been the downrange wad that did it for you. Surely it could not have been the reclaimed lead shot that I sold you. Terry
