Messing around while bird hunting with the Browning, I can get off 3 shots from the hip in a bit aver a second, call it a second and a half max. Aimed shots from the shoulder, are slower at 3 shots at say 2.5 seconds. I don’t think there’s a pump made that can match that plus there’s always the risk of short stoking into a jam.
It frustrates me to no end that 16ga shells are so rare to find on the shelf. I am much more accurate with the 16ga as the 12ga has greater barrel rise so takes longer to get back on target plus there’s the added gun movement just from the body motions of racking the slide.
At Sportsmans Guide they have 16 gauge buckshot, slugs, and birdshot.
Oops! Sorry, all out of stock!
I have a had several semi autos. My favorite was a Beretta Model A606 Sporting Clays.
Every now and then it would pull off 2 shots on one trigger pull, usually with the 1-5/8oz 6 shot loads.
