IMO the biggest glitch in this forum is adding pictures for this "too big" reason. I just had to reduce a picture three times recently to get it to post here on a different topic. Very frustrating. I found a few sites that will reduce a picture for you fairly easily. What often happens is that my pictures end up posted to two other forums and not this one. A true computer nerd can probably help you. I just stumble around until something works. If I have a picture that is in my file with "redo" or "resize" added it is because of this forum. I'll add one of my 410 pattern at about 30 yards. Just as personal preference I don't normally pattern any gun over thirty. I've hunted these big birds since the 1970s and most shots have been 25 to 30 yards. The one shot I've taken this year about 27 paces. Good luck.
BTW - this is with a Stevens 301, Jeb's choke, and Apex 9 1/2 shot. I added a Sig Sauer Romeo 5 red dot this season. I'm well pleased with this combo.
