View Full Version : Throat issue on Kimber Gold Match

I wasnt sure if this is the correct location for this, mods pls move to approprate board if needed.

I recently picked up a Kimber Gold Match II. I love the gun, wickedly accurate, but I had some issues with my reloads. It appears the throat has a sharp point on it that catches the case lip, causing a FTF. See attached pics. This happened several times today. Each time, I took a marker and drew the outline of the barrel hood on the round. I lined each round up to the barrel hood and where I drew the outline, and each round had the same bad spot in the same location, which matched perfectly with the sharp point on the port side of the barrel throat.

I ran about 20 rounds of OEM ammo through with no issues, so I'm wondering also if there may be something I should differenty with my reloading.

I compared this barrel to my Kimber Custom Classic Target, and it has a much smoother throat, with no point on it.

So my questions are:
- Is this farily normal?
- Should this be smoothed out? If so should only a gunsmith do it?
- Would a longer OAL help? My loads are currenlty 1.235"

You might want to try a taper crimp die. Looks to me that you still have small gap between the bullet and the case mouth in your photograph.

....Or perhaps you need to break the edge between chamber and barrel ramp with some 600 grit sandpaper?

Ivan seems right on the money. you might do both. your oal isn't the problem

Yes you could smooth the sharp edge. Little at a time. I'd also second a little moor taper crimp
