I worked up a load for my 7mm-08 using ramshot big game and barnes 120 TTSX this year right before hunting season. I tried using magnum primers when I was testing loads with this powder/bullet combination because I had read on here where some were getting very good accuracy with big game and magnum primers but for me the results were not that great. When I tested the same load using a Winchester large rifle primer all 3 shots were touching so that is what I settled on. I'm hoping that if I test this same load using CCI 200 primers the results will be the same because I'm running very low on Winchester large rifle primers.
