The last few range trips with my 1911 I noticed a new problem with the primers. They started to show primer swipe, sometimes it even raised a burr that caused trouble with the shell holder.
Load is a 200 swc from an MP mould, 4.8 gr of Promo, and a Tula LP in mixed brass.
I looked online and found some info making me think it is a recoil spring/firing pin spring issue. Since I had a couple spares of each on hand from Wolff I decided to make a swap. Firing pin springs looked the same but boy was the original recoil spring a bunch weaker and shorter. Getting the recoil spring plug in place took apparent more effort as does racking the slide.
I used a 16# Wolff recoil spring and the extra power firing pin spring that came with it. Will try to get out before snow flys to see if it makes a difference. Hopefully it helps tame brass ejection a bit too.
