The shotgun stage has always been where I've lost all of my ground. I've always placed 1st or 2nd in the pistol stages, and very high in the rifle stages. My overall placement has been 2nd (overall) every time.
I do need to improve a bit with the rifle (10-15sec.), and I'm constantly training with my pistol, but I've always been at a disadvantage with my pump-action shotty. There are guys on the field who sport semi-auto's (10 shell capacity) in concert with speed loaders. There's no way I can keep up with them with my Mossy. I think the advantage I get with the Saiga will make it possible
