No question the guy in town doesnt have a clue as a 270 is a great deer round.
But like Plainsman I have a 1944 No.4 Mk1 and love it. It drops deer every year without a problem. I will say its not a long range cartridge though but where I hunt shots are typically 150 yards or less and the .303 does a fine job.
As for accuracy I'll shoot against anybody with anything modern with open or peep sights and 9 times out of 10 I walk away with their lunch money.
