I recently picked up this shotgun. It is an SAR Semi Auto Special Purpose Shotgun (SARSASP)- Sarsilmaz and i have a question on which ammo to use. I pucrhased a box of Winchester (silver box i believe) 2 3/4 7 shot from Walmart and my first time out, the semi auto shotgun was reduced to a single shot. Needles to say i was VERY disappointed. Took it my my LGS and the gunsmith there said it was the ammo. He fired 5 shots through it using a brand called RIO? that was also 2 3/4 but was 7.5 shot and it ran perfectly. Basically he said the ammo sold by the big box stores cant generate enough gas pressure to cycle the bolt and eject the spent shell. So i bought three boxes of what he used and will use it for 3 gun competition but i want to get a good brand of 00 buck for HD. What should i pick up? Sorry for the long post but wanted to give some background. Thanks... Wanna kill these ads? We can help!
