Have (2) of the same steel receiver B-80's, and (1) alloy receiver 2-3/4" B-80. The alloy receiver trippled on chukar's the first time ever fired, but I must admit the footing was on relative "flat" ground. It was during the early season opener we used to have in the Tarpiscan. My 1st gun purchase at 13yo, a 20ga 870 (mag) LW, did the same thing but the footing wasn't nearly as "flat" then, as I was on a steep talus slope during an early chukar opener.
