As the title states, which one are you shooting and why?
Love the 28. Last October several of my cousins got together for a family sporting clays weekend. Shot 3 rounds of SC at Sportman's Trianing Center outside of Wichita KS. Due to shoulder replacement surgery in June, my Dr. hesitantly released me for the shoot, as long as I limited recoil. Therefore, I took my SBE3 28 gauge and planned to shoot it all weekend. First round was rough as the SBE3 is light and whippy and I only shot 55/100. All my cousins were shooting 12 gauge and their scores were in the mid 60s. Feeling a bit down, my cousin suggested I shoot his Citori 725 28ga with 32" barrels. Being very simiar in fit as my CXS 12 ga, the gun fit me well and had great weight. 2nd round I shot 71 and my cousins slipped into the low 60s. 3rd round the next day, my cousin suggested I shoot his Beretta A400 28 ga. Again light gun, but heavier than my SBE3, and I shot 62, and my cousins were in the high 50s/low 60s. I think for the weekend I ended up high overall, except for my cousin that loaned me his guns, he is a master class SC shooter and he was in the mid to high 90s for all three rounds. We didn't include his scores with my other cousins and me for our family competition, as we are amatuers at SC but have done a lot of hunting together. My other cousins are great shots when hunting.
I think it psyched out my other cousins a bit on the second round when I was shooting the Citori 725 so well. May have helped contribute to their lower scores. They are a bit on the competitive side.
With the correct gun setup and shooting targets at reasonable ranges for a 28 gauge, the 28 is just as effective as a 12 gauge.
