[QUOTE="Sage70, post: 2231583, member: 119027"] Mashburn Arms Company had their business located on Pennsylvania Avenue in Oklahoma City back in the 1960's and they were building many custom rifles for Mashburn improved chambers. I had them build a 25-06 Mashburn improved in 1965 on a FN Mauser DeLuxe action and it was a real shooter. I had this rifle built before Remington introduced the 25-06 with the standard 30-06 shoulder. My rifle used a 30 degree shoulder and my reloading dies were made by RCBS. Your rifle could have that same 30 degree shoulder. Also, the Mashburn case has a straight taper so the diameter of the case is the same from the web to the shoulder. That explains the comment in post 59 about the base diameter being large. Mashburn load data was quite hot and that explains the split cases but after all the increased case capacity was intended for higher velocity and case life was short. In 1965 quality rifles were not known to blow up and no one was concerned about shooter safety. I fire formed many cases in that rifle just like you would do with the Ackley chamber today but the shoulder was not blown out quite as steep. Your rifle is very strong and can handle the fire forming without any problem. I think even today you could fire form a cartridge case and send it to RCBS and they would make you a set of dies.
