I have a Model 95 mauser 7x57 , picked up in , at all places Montgomery Wards, I sporterized it and hunted deer with Remington factory loads , 175 RN loads. Then I started casting, Lyman #287641, 160 grain with a gas check, and because of the long throat, it will handle long heavy cast boolits with the base set at the neck-shoulder junction. I don't like to seat the boolit base past the neck , and they will fit into and feed from the magazine. 14.0 grains of Unique would get 1600 fps and was as accurate as I could shoot with iron sights. The first three shot group , off hand, and it was getting dark, at 50 yds. , could be covered with a quarter (two shots touched , the third was 1/4" from the first two ) and it was to point of aim ! Yowzer.....That was "THE LOAD " for that rifle. I still got it too.
