I'm reloading for my savage in 300 win mag and I'm going to be using H4350 powder and am loading a 200 gr. LRX to try and develop a new load. I have about 1000 Remington 9 1/2 M magnum rifle primers and about the same amount of Winchester large rifle magnum primers. I'm wondering if there is a difference in performance between the two brands and what more experienced re-loaders prefer to use. all responses are welcome. thanks
