Wildcat Update! Excessive wear on the polymer receiver?

I run 500 rounds through the Winchester Wildcat to see if any excessive wear from the steel bolt, can be detected in the polymer receiver. Only a total of approx 800 rounds have been ran in this rifle currently but I'll take a close look to see if there are any signs.
