My load of 52.5 gr. of reloader 19 is certinly a hot load and is to be built up to. I cannot fit any more of that powder in the case. I shoot it out of a ruger 77mkII, but i have shot it out of a winchester 70FW, Remington classic, and a mexican mauser. Extraction is fine, the primers arnt flat, and there is no excessive case streach of primer pocket deformation. Results may vary, but it has proven very acurate and hard hitting for myself and those i have loaded it for.
