My 50's all have the ramrods (700 ML/MLS, Savage 10ML2, A&H420 etc)... I leave them in and use a range rod to load/clean so that the rifle shoots consistently with the rod installed. I keep the range rod in the truck if I'm hunting somewhere other than my own land (rare occasion now-a-days).
Only use the rifle's rod if I have to do some sort of field reload away from the house/truck... but that is a rare occasion. Or I use the rifle's ramrod to check if the rifle is charged as each has a witness mark for their respective rifle/barrel.
My one 45 MLS came as a barreled action that I build up into a Boyds stock... thus no ramrod installed.
