bought some federal 1 3/4" mini shells 1200fps in #4 buckshot 15 pellets to try, I was surprised how they patterned compared to the 2 3/4" #4 buckshot, 1325fps 27 pellets. range work show the at 20 yards all 15 pellets on a 8x10 sheet of paper constantly for 3 shots as the 2 3/4" 27 pellets would score 14, 14 and 12 hits. The 2 3/4" was a filling removing round while the 1 3/4 was very pleasant to shot and follow up shot was easy. anyone else using these, make a 8 shot gun into a 13 shot gun
