Shotgunjones; I use the BPI also. Just recently I got the insert into a RST 2 1/2" 16ga 1oz load recipe using the SG16 wad which it called for and it pie crimped nicely after I pre-squished the wad before the insert, but it came back up to within 1/16" of where it was. You have to wiggle the insert a little to get it in. It gives better distribution of shot than the Polywad but doesn't spread quite as much.
Using the same recipe with 15/16 oz in one of my Elsies, which is the only one I was patterning, gave a 22" effective pattern out of a barrel that gave 17" non-spreader. The choke was .025.
