Well goldie this is the deal if your gun dosent shot very well with the choke you have then you will need to get another. Every gun is different. The ventilator shoots well out if my 870 but does not shot worth a s!@# out of my 11-87. The Rem super full shoots great out of my 11-87 but does not shot worth a s@#$ out of my 870. Buy the choke and try it out.
