I will have to back and read what I wrote to him what I wanted. I know I told him I wanted this rifle as a varmint/coyote type of rifle. I forgot if I mention the 50g weight bullets or there abouts. However he told me he put a 1/8 twist and that this twist will also shoot lighter bullets as well as heavy weight bullets. I do not recall if I specified a twist but I highly doubt that folks who are going to shoot the standard 40/50/55g weight bullet would want a 1/8 twist unless they were going for heavier than that. I am not planning to get a mil-dot and throw heavy bullets in an arch 1,000 yards away. I am going to shoot this rifle and see how it shoots but one of the previous poster stated but I think bullets "wandering" to get to the pipehole will be off center.
