I wouldn’t worry about the pushfeed, but I would worry about the enclosed trigger. After suffering numerous freeze ups (mostly on Kodiak or Montaque) I sold all my 700’s and went to mainly Savages and Winchester 70’s.
In the cold they were OK
In the wet they were OK
When it was cold, wet, and temps running 20-32 degrees they were not.
This, exactly. M70s would be best. Can't say about Savage and their Accutrigger. The new Rugers would be good, too, with their open trigger design. Enclosed triggers in the wet and cold, not what I would want to bet my hunt on.
