I'm dealing with a unique failure in the Limited Pro I am in the process of Tuning up.
I will spare you the details of how I came to this conclusion, but long story short.... I am getting light strikes on 147 Grain Bayou Coated Lead rounds in Double Action. Single Action goes bang every time. The unique part is that I have 100% reliability in Double Action with 147 Grain Xtreme Plated. At first I thought the issue was my short chamber because I noticed some of the coated rounds don't plunk (that may still be part of it). I ran a test with 20 coated and 20 plated in Double Action today. 6 of the 20 coated didn't go bang. Surprisingly all of the failed rounds plunked in my barrel just fine when I got home. I have a couple of theories on what I should do about this, but I would love to hear your opinions in case I'm not thinking of something.
Current list of Modifications:
Bolo Connector
Xtreme Sear
Patriot Sear Spring
Patriot Trigger Return Spring
8# Recoil Spring
Henning Extended Firing Pin
Patriot Optimized Firing Pin Spring
Patriot 14# Hammer Spring (Using Federal Primers - They should pop all day at this spring weight)
Theory #1: Need to ream the chamber
Theory #2: Recoil Spring is too light. The failures chamber slightly out of battery (see off center strikes in picture). The Plated RN run fine because they feed better?
