Heres a picture of a Red Stag shot by my son last Roar. Alec shot it at approx 150 yards with my win 85 Hi Wall 38/303. The bullet was a CBE 375-300GC Flat nose. the load is 37 grains ADI 2206 for 1940 fps out of the Hi Wall's 30” barrel.
The shot was side on thru the near shoulder blade & 1 rib then breakng 2 ribs and exiting just behind the far shoulder with a 1 and half inche hole. At the shot he staggered 3 paces and dropped. then stag never moved. It was typical preformace that I have had these loads in the 2 38/303s that hunt with. The bullet was cast from wheel weights.
