Testament to Impact 737Rs...I left my bolt behind on Day 1 of a 2 day PRS match
A good friend that shoots Impact shared his bolt with me....he'd shoot the stage..then lend me his bolt so I could shoot the stage. Got through the day, my gun shot excellent with his bolt, couldn't tell a difference in cock on close or any other interaction with the rifle.
Measured fired brass after the match with my finish reamer custom made chamber gauge...within my tooling and abilities to measure...I called it identical to the fired brass I had from my bolt leftover at home with the same number of firings.
I know I've heard of other Impact stories like this. No doubt other actions this has happened, just sharing
