I very much appreciate the information so far. I would like to digress for a moment, when I bought the rifle it was pictured with a set of RCBS dies Marked 350 Brown. The dies never made it for whatever reason. The rifle is Marked 35 Brown-Whelen on the barrel so that's the dies I ordered from CH4D. So far I have done the following, sorry if this is long. 1. Did the expanding to 375 then the 35 BW die it does chamber on the doughnut verified by using black sharpie to color the doughnut and it has a ring all the way around. 2. Just sized 2 brass in the 35 BW die only and tried the backwards 38 cal bullet will only close the bolt with bullet seated barely below the case mouth. Tried one with a 200 gr Remington Soft point Corelockt bullet and the bolt will close with the bullet seated 1/32 below the cannulure. Considering doing a chamber cast to check for sure. I have another Wildcat I have to cast anyway. Thoughts ?
