I am not sure if you mean 300 rounds as we shoot here in south Alabama or if you are referring to 3D type shoots. We shoot 5-Spot targets indoors through the winter to get ready for the 3D season comping up this spring. We have several shooters that can consistently shoot 299's and 300's. I have only managed a best of 297. My goal is to shoot a 300 with at least 50 x's even though I will probably not ever actually do it. Still, it is a worthy goal and I can keep shooting until I do. Good luck and shoot well.
