Hoping somebody has some tips to save my shooting coat. I have a Freeland Cordura NRA shooting coat that's around 8 yrs old (wow, time flies!). The grey rubber patches have been polished, or developed a glaze that's created a real problem keeping the rifle butt in place, or keeping my right elbow from moving in rapid fire. It's funny how this problem has been creeping up on me over the last couple of years without me realizing it, affecting my position and the way I sling up, in an effort to compensate for it. The days of watching the front sight come up and right back in rapid are a distant memory. Can it be saved or is it time for a new coat?
