I have been using Hornady steel match, Nosler custom 60 gr and AE 55gr Fmj through my WK180C since I got it and have about 300 rounds through it without a problem.

The other day I bought two boxes of Hornady 55 gr vmax. I fired a 3 shot group with the AE 55 gr to foul the barrel as I just cleaned it. After letting the rifle cool right down I loaded up 3 rounds of the Hornady 55 gr vmax. 1st shot fired but didn’t eject and I couldn’t get the empty case off the bolt face. I split the gun and pulled out the springs, guide rods and bolt. Here the primer had protruded so far out of the case it was hung up on the bolt face. After getting the spent shell out I put the rifle back together and loaded up 3 more. Of these 3 shots one primer had came out about 1/3 of the way and all 3 primers had been pierced. I loaded up two more rounds and had the same issues.

I’m not sure if any one else has tried this ammo in their WK180C but it definitely doesn’t work in mine. I then went back to using the AE 55gr and fired another 40 rounds without a problem.

Just took my WK out today with 100 rounds of Hornady 55 grain v-max. I made out fine until round #98.

This is how all of the first 97 looked after firing

Ya that's unburned powder in the chamber and the bullet stuck in the bore just forward of the chamber. I've shot over 1500 rounds of the Hornady through semi-autos (mostly my xcr-l) and this was my first dud round.


I use the Hornady when shooting a lot because it isn't priced too bad yet but if you're looking for a factory .223 round for yotes etc. you should pick up some of this stuff to try

The Federal Premium isn't cheap but it is far better ammo than the Hornady. I only use the Federal Premium in my MV and it is more accurate than the Hornady.

I'll have to give the Federal a try in my 180-C
 
***EDIT***
I just found one of these in my brass that I didn't notice until I looked closer

You can clearly see the primer protruding where the pin struck it. This is the only round out of 98 fired.

On all the other brass it seems the firing pin mark is very deep. Possibly soft primers in the Hornady ammo?

Yup that’s what mine look like except with a little more black around them with the exception of one that the primer came completely out. After pulling it apart it looks as though the flame has damaged the tip of my firing pin and burnt the plating off it. I have sent pics of the ammo and firing pin to Kodiak Defence. This Hornady 55gr vmax is the exact same velocity as the Hornady Steel match that works so well in my rifle.

Thanks for posting Smokinyotes.

Although I got through more rounds than you mine does show signs of issues and I will definitely discontinue using the v-max ammo.

I'm going to give the Federal Premium NBT a try and see how it goes. I've noticed before that the Federal is better quality ammo than the Hornady.

Sucks that you're firing pin got damaged because of crappy ammo
 
Took WK TO THE RANGE TODAY;

Also experienced major extraction issues shooting Federal off-brand 5.56.

Mangled rims, and 15 failures to extract in 100 rounds. Bolt got stuck in chamber multiple times, with fired and unfired rounds. Took lubrication the bolt while partially in battery and strikes onto the charging handle to release. Firearm was lightly greased with Automatenfett prior to shooting.

Had a couple blown out primers too.

Is this a headspacing issue?

check your bolt head, does the firing pin hole look a little bigger than it should be?
 
ALSO:

2 screws on hanguard came loose while shooting.

Castle nut holding buffer tube also came loose.

Was shooting seated, with a bench rest.

Fair to say my first experience with the rifle was not particularly good.

Took a chunk out of my knucle on the gun, trying to slam the bolt back, and a couple times trying to force it into baterry.
 
Multiple stuck casings. Primers blew out 2-3 times.

Is this rifle safe to shoot?!

Not sure if yours has a head spacing issue but mine has had absolutely zero issues until I tried the Hornady 55gr vmax which leads me to believe it’s an ammo issue as everything else has worked great.

It very well could be. It seemed like the 20 rounds of .223 Winchester white box 55g worked flawlessly. I question if any ammo, can catastrophically fail like this though and it ONLY be the ammo. 20/100 rounds is huge.

It doesnt seem to like to strip/chamber rounds off steel mags, when bolt is released from the rear-position. Springs dont seem to have enough power.


PPS - The trigger is probably the worst, most unpleasant trigger I've ever shot. Heavy, sticky 3 stage trigger would best define it. Any suggestions for easy install alternatives?

It very well could be the rifle. Contact Kodiac Defense, they will take care of you.
 
HotSoup, if you look at the primers on fired rounds that still seem ok does it look like the strike mark from the firing pin is normal or does it look to be a little on the deep side like mine?

I was thinking soft primers on the Hornady ammo but the more I think about it I'm not so sure seeing as I've ran a pile of it through other rifles.
