CDR- snoop around the website a little and you'll find stuff that rivals the TSS stuff as far as weight goes.
As far as a #5 replacing a #2- Im skeptical to say the least. Not that its impossible, or even unthinkable, Its just that darn cool.
For what its worth, I Have done some 1.25 oz stuff with the BBB that pattern wise rivals the single b 1 3/4oz hevishot 3.5 inch goose loads. Patternwise, shooting 5 shells of each It was bascially identical performance with 13-16 pellets in an 8 inch circle at 50 yards. The 7.5's did penetrate the 1/2" plywood backer board at 50 while the number 4 hevishot did not. This could be interpreted several different ways, but seeing how the 7.5's had less surface area and less resistance, I just focused on pattern performance, and Yes, Id shoot a coyote at that distance with the 7.5's with utmost confidence.
