I did some test's Saturday with # 8 and 00 buck on 3/4" plywood. Tests done with Rem 870 w/20" barrel. Winchester Super Speed #8 birdshot and Remington Express 00 buck.
I had 3 sheets of 3/4" plywood set up back to back.
Result with #8 shot:
At 5 yards all pellets stopped in first sheet. Same at ten yards.
Result with 00 buck:
At 5 yards, all pellets penetrated first sheet, and 8 of the 9 pellets stopped in the second sheet. One pellet stopped in third sheet.
At 10 yards, all pellets stopped in second sheet.
Much more pellet deformitty at 5 yards than 10. Recovered pellets from 5 yd were flat or twisted elongated. At 10 yds, the pellets were semi-rounded.
Disclaimer: Of course everyone's results will vary and don't expect these results in real life scenario. These are my results with my ammo.
