Hello,
Years ago I was shown RWS brass from Germany, little known here. A fellow writer took the 6.5 x 68 RWS case wildcatted it, necked down to .25 caliber, called it the Banshee and obtained 4,000+ fps with a 100 grain bullet, which impressed me.
I noted the 9.3 x 64 RWS cases fit four in the magazine of a rifle similar to a 30-06, but they were larger cases. I designed a wildcat for this case necked to .30 caliber and was pleased when the cartridge with 180 grain bullets, attained .300 Weatherby published ballistics in my Krieger barrel. I noted after two firings with 76 grains of Retumbo the brass was so strong it had not fire formed yet to the chamber's 37 degree shoulder, but still resembled a weatherby-like venturi shoulder.
Retiring to northern New Mexico, I decided to use this barrel for long range hunting here. Utilizing a Remington action required modifying the brass due to the diference between Remington and Savage boltfaces. I sent off the brass to the gunsmith for modifications and the RWS brass disappeared. I ordered new RWS brass and we went through the complexities of converting that brass to fit my chamber.
I went to the range and found out totally to my suprise that the cases fire formed with the 37 degree shoulder on the first shot, with this new brass. How could this be?
Is ther anyone out there who has some idea of what has happened to RWS brass over the 12 year period since I purchased my first bunch? I enjoyed this experiment in which I had created a cartridge that had "06 magazine capacity and 300 Weatherby like performance. Now I might have spent a lot of money and time creating a case which can no longer deliver the performance I was so proud of 12 years ago, when I used it in long range benchrest competition.
Thanks for your attention in this matter,
Gene
