I use them out of a Win SX2 26" bbl with an Indian Cr 665 and have patterned a BPS Upland Sp with 22" bbl. The BPS shoots them well with the Indian Cr, a Carlsons 670 & the Invector Plus Browning Full Choke. I shot them at 40 Yds. I didnt count the hits in a 10" circle but the pattern is uniform and pretty dense at 40 with each choke, much more than any of the shells I've tried. I know the Win will kill turkeys and am confident the BPS will too ( I just bought it and will try it this spring )
I have some Hevi 13 3" with 2oz of #7 coming that I'm going to try too. They may have more pellets but I dont think they will kill a turkey any more dead than the Blends do.
