I just got a new Remington 870 Express Black Synthetic 18" 7 shot last week, I'm just curious what the best loads are for blowing things up and ripping big holes in things, I have shot the following in the past and the last two recently for the first time out of a friend's Mossberg 590, standard 2 3/4" field loads, Remington 3" Magnum 1 Oz. Sluggers and Remington 3" Magnum "#4 Shot Turkey load" i think. The last two were fun to shoot 2 liter soda bottles with and nice effects on an old TV. I figure buckshot would tear some stuff up nicely. Anyone care to share their favorite go out and blow stuff up loads? I'm also interested in knowing what the hardest kicking 12 Gauge 3" Magnum shell i can get is, yes i wanna try it. Cause i didnt think the 3" Slugs or Turkey loads we shot were all that much after being told forever they were. I'm interested in hearing about 00 Buckshot and 000 Buckshot, number of pellets, etc. Thats about it, thanks.
