I have a "target" rifle a friend built for me out of an Type 38 Arisaka action. It seemed like a good Idea at the time I bought a Shilen 10 twist .30 cal blank and he fitted it full size to my action. He fit an aluminum block to the barrel just in front of the action and bedded this in a rem 40 x bench stock that was channeled and fit with an aluminum strengthening block.. The rest of the barrel and the action are completely floated. It also is fitted with a Timney featherweight trigger for a mauser. Scope is cantilever mounted to the bedding block. Looking to shoot only cast I chambered it in 7.62 X 39 as this seemed like a decent easily had case and I have a nice supply of REm and Lapua brass. We never got aroungd to Lenthening the throat to fit my boolit. I have a 150 LBT and a 170 lbt both are full diameter boolit designs. I cannot find much information on throater specs. If I have to have a custom made I am not sure what would be the most cast friendly design. Would I want to send the reamer guy a boolit and let him decide? I got gun out and messed with it some yesterday and man does that case have a short neck! I have plenty of room to rechamber to something else but I am a tightwad and do not want to go with too much of a custom sesign. I liked The idea of using a short chambered .30-06. and cutting down dies to match. Any sugestions, comments about this? I know I messed up with the 10 twist but I will live with this.
