I just went skeet and trap shooting last weekend to sharpen up for the upcoming bird season. I used my 12 gauge semiauto and had some what of a successful day. I also brought my 20 gauge o/u and shot that as well. My question is this, it seemed that I hit just as many birds with the 20 gauge as I did with the 12 gauge, is there something going on here that I should know? The 12 gauge has more bbs than the 20, so doesn't that make the shot easier? Please advise.
