If you have a rem870 dont buy the Winchester cheap bulk pack ammo from walmart. They have close to a 50% jamb rate after fireing in my new 870. The cheap bulk federals in the same packs right beside them same price, not a jamb in the last 100 rounds i shot??? The others would jamb the action at least one time in the 3 shot cycle when dove hunting.
As far as recoil, if your at a range shooting yea shot low recoil stuff to not be all beat up, but load that thing with the real deal. If your ever going to use it you wont notice the extra kick, even if you unload all 5 in four seconds you wont notice the kick till the next day!! Your adrenaline will be running so fast it wont matter. In a case like that i want that shot to have as much velocity as it can, to tear through what it has to. So what if i shoot holes in my windows doors and ruin my drywall on 2 sides, thats the least of your worries!!! You can always claim insurance at that point from theft i guess?? Its like when i target practice with my 30 06 after a few shots you can sure feel it, but in the woods even after 3 shots close togeather you dont even notice it.
