At my last Silhouette match, our match director picked up some 270 win brass and said to me to use it to make my 7.7x58 Jap loads. I know that 30-06 and 8mm Mauser brass will work and that 8mm requires less work, I have not heard about using 270 brass. Even though the 30-06 was the parent case for the 270, I have not taken the time to compare the two.
Any thoughts
