Canuck Elite TacOp - First 50 Shells

[u/ElectronicPrize9514]

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.

My own Turkish M4 clone had a small burr on the feed ramp that hung up three rounds during the first 80 I shot through the gun.

I applied ​60 seconds of sandpaper by hand, followed by ​3 minutes of Dremel polishing with the soft wool attachment and some Autosol metal polish cream.

It runs smoothly and reliably now, no failures to feed.

Maybe your shottie will benefit from similar polishing. ​

As I was cleaning it tonight I found a similar sharp burr near the exact same spot. I found it by slicing my finger lol.

Ill try something similar. Im a little nervous about altering the firearm. Im new to owning guns. Worried ill over do it and cause an unfixiable mistake.

I was scared too when I was first told to "do my own lapping and smoothing."

Now that I've polished the feed ramps on four shotguns, three rifles, and a pistol, I feel good about this polishing being good for the gun.

-the goal is not to remove any crucial metal nor change the barrel geometry. Instead, you are revealing the correct​ geometry by removing imperfections that were missed at the factory. ​

Nope it's the shotgun. Clearly a burr on the feeding ramp that needs filing down. Shot several hundreds of rounds of challengers and score ammo and never once had this issue. Infact I shot a box of these exact same score 00buck yesterday out of my mossberg 930. No issues.

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

My 1301 eats score and challenger all day.  Never had a failure.

Shut up with your good shotgun and competent purchase you're not wanted here

Friends don’t let friends buy Turkish. 

[u/EnvironmentBright697 → u/Vegetable-Army-4872]

That’s what you get with the higher end shotties. Better QC and machining so you don’t have to do it yourself. If you’re gonna buy a turknelli some polishing is required.

Don't forget metallurgy 

[u/ElectronicPrize9514 → u/EnvironmentBright697]

Unless a Dremel and some polishing compound is going to cost me $1300. Im okay with that trade off lol

[u/Vegetable-Army-4872 → u/ElectronicPrize9514]

I think $1300 is a very good deal for the peace of mind knowing that your shotgun will always work when you need it to.

From my experience is a combination of both. I have challenger shells like that and they don't run right in any of my shotguns simply because the shells aren't crimped right. But at the same time I had to polish out my turknelli feed ramp too
