I like rifles to have the same maker as the cartridge (not that I could ever afford a 375 H&H in that case!), but for the ones that it’s doable I intend to strive for such. Example - if I wanted an RWS rifle I’d get a 10.3x68 RWS, if I wanted a blaser (and I do!) I’d get a .45 Blaser (it’s on my want list).
