How to break in stoeger m3000. Jun 25, 2013 ยท I cleaned the packing grease out of my M3000 (Black synthetic 28"), and my first time shooting it was for skeet (bought it 2 weeks ago and shot it yesterday). Break-In Period: It’s essential to understand that Stoeger M3000 has around a 100-200 round break-in period. This will prepare the shotgun for cycling light trap or hunting loads. you can do this by opening/closing your gun after every station in skeet/trap, that way you are opening the gun 2X as much. Fire 100 to 200 rounds of a heavy load through the gun. If you experience initial functioning problems with 1 oz loads, we recommend firing three or four boxes of standard hunting loads to allow for this break-in period. Immediately after purchase, clean the gun and oil it thoroughly. Use a heavy hunting load and put 100 shells through your new shotgun. The only break-in i've ever heard of was the breaking in of the action, which is often difficult to open on most O/U's when they're new. . iobd terxlf dfg mhrco vllt xuhwvms qtnzsv rddefh ianvtnu abk
