Here's a typical jam.

The bolt has over-ridden the next round, due to short stroking and has also failed to eject the empty casing.

Here's another jam.

In this case, the empty was ejected, but the bolt did not fully go to the rear and failed to pick up the next round. Instead, it has over-ridden the round and jammed.

Just in case anyone thinks I am down on Wolf, we also brought a couple of our ARs and shot several hundred rounds of Wolf .223 with not a single problem.

Wolf in .223 is slightly down-loaded compared to US commercial ammo, but it is just fine for plinking.

And, it is cheaper than anything else out there

Here's a pic of the feed ramps and chamber after 100 rounds of Wolf .30 carbine.

As usual, it left some unburned powder and carbon residue in the chamber, due to the steel cases not fully expanding and sealing the chamber.
