I was trying out my new hand loads through my Kimber TLE RL II yesterday and they were great. They

functioned 100%. Then I tried some Speer Gold Dot 230gr I picked up a while ago just to see if they'd

run through the gun fine. I repeatedly had this issue where on the last round the slide would lock back

but the round would be in the chamber. It was out of the mag, and it fed into the chamber, but was just

kinda hanging out. A couple times it failed to go into battery.

 

I was able to replicate this problem consistently if I put in one two rounds the top one being a Speer Gold

Dot.

 

It then dawned on me that a while ago I changed out to a lighter recoil spring. I believe either a 16 or 14lb.

 

Do you think this is what is causing the malfunction as the Gold Dot is pretty hot ammo and the light spring

is meant for my light target loads?

A lighter recoil spring can definitely induce bad feeding. When I owned my Colt Match Target a while back, it actually came with two recoil springs. One was for target loads and the other for standard ones. Give it a try with the standard spring. I bet it will work just fine.

With lunker on this. Use a standard spring.
