Fix my gun Canuck Elite TacOp - First 50 Shells

Post image

Hello! First post. I have a turkunelli clone. After first 50 shells (score 00 buck) I had 5 malfunctions. All of them failures to feed. The shells were damaged trying to be fed. See picture for example.

​

Thoughts? Is this something that may resolve itself as I continue to break the gun in?

It's not the shotgun. It's the shell. Notice the divot is at the point of the crimp??

Challenger 00 buck have this problem. The crimp isn't fully rounded (basically a hexagon) and the corner catches on the feed ramp, stops and gets destroyed by the bolt. Most slug rounds don't have this issue since the edge is rolled in and not folded over.

Work in your Canuck with a box or two of magnum slugs. Avoid cheap shells with that terrible faceted crimp.

Once I realized using this cheap ammo caused this issue, my Panzer M4 Speed Pro runs as smooth as butter. ZERO F2F, extracting, or stove-piping.

Edit: OP needs to see if it's a burr as BowFella mentioned below.

I have fed all kind of junk to my Benelli M4s and never ever had anything like this. I've used score slugs, score buck, challenger target load, challenger slugs, never once had ripped up shell like this.

So I'm not so convinced it is the shell crimp
