It's good but shoots really really tight. If hit you hit birds at close range and center the pattern, there won't be much left even with an open choke. It should be a great load for later in the season when longer shots are needed. Here's what my pattern test showed.
"I shot a number of patterns with 12 ga. No. 6 2 3/4 inch Prairie Storm last week. I used Imp. Cyl. in a SBE shot at 30 yards. The patterns looked like I used a full choke, very tight. The spread was 16 inches with lots of center density.
It would really hammer anything you hit with it. It's probably due to their flitecontrol wad. It has a solid cup, no slits."
Lock and Load!
