It depends on the choke and the number and size of your choice of shot. Only use a full or extra-full choke. Bigger shot such as #2 travels farther but there are fewer pellets in the load so the pattern may be spotty at ranges exceeding 35+ yards. Smaller shot like #6 has many more pellets but the energy falls off faster and they won't reach out as far.
I like a full choke with 3" #4 copper-plated shot. It is a good compromise. I still keep my shots within 40-45 yards. Hevishot will kill at longer ranges but is VERY expensive.
do you use chokes?either way you should as with any firearm,shoot and pattern your gun with the loads you plan to hunt with.then you will know how far you are able to shoot and make an etical shot.different chokes and loads or brands pattern differently.hope this helps.
I suggest that you take and shot a target at 30 yards and see if you put 8 pellets in the kill zone of a bird. Over the years I have found it best to pattern a gun before taking it hunting. I like to show targest at 20,30, and 40 yards.
I always suggest to never shoot over 35 yards. I realize that with certain choke tubes and shot combos you can attain a good pattern at longer distances, but after 35 yards even the best patterns start to break apart. Good luck!!!
