Not wanting to open a can of worms here but trying to decide on an all weather straight wall cartridge. Have a 45-70 and 444 but would like something to use in rain or snow. Was initially looking to buy a 444xlr but it's nearly impossible. Thinking a 450BM or maybe a 350 legend. Would like to be comfortable out to 300 yards. Not finding many rifles in-between the entry level(axis, RAR, etc) and something like a Christensen Mesa. Any advice or thoughts?
