Question on primer in th 375 H&H. I am using the hornady 270gr apire point with 61gr. H4895 being it is magnum cartridge do I have to use a magnum primer or can I use a federal(210) large rifle primer. My reason for asking is that I have a lot of large rifle primers but no magnum rifle primers. Not a big deal to go out and get them but just wondering. Thanx :grin:
