I'm sure the m-burg will get the job done... I can still see my buddy trying to get his to pattern at the range back in the mid 90's... I hate to admit it but I got a lot of chuckles behind his back... He was hard headed!!! Till this day that gun wouldn't touch my 870... But I do have a box with a least 10 chokes and a shell cabinet with every brand of turkey load in it lol... So I guess it boils down to how serious you are to have the best patterning gun you can have... I was serious and he never really was... So get the m-burg and play with it and I'm sure it will get the job done
