ive always stuck with winchester cases during my loading career, however due to my own fault, i unknowingly bought rem. cases last time for my .45acp. in this & other forums, ive heard reports of thin walls, loose bullet grip, etc. i load a case 6 times only before pitching & keep my hardball recipe to 800 fps. what are your experiences on rem. 45acp cases & will they keep proper bullet tension for 6 loadings to prevent setback?..thanks
