“Ran two bricks of the SK Flat nose target 22lr through a Ruger M4 Hunter with a Volquartson bolt tune up kit and found two issues with this product. The flat heads were not always flat but had malformed noses which caused the bullet to jam into the ramp. these cartridges also produced more stove pipes than I've had with any other brand.
If you are looking at these cartridges, I suggest you move on. I was charged a premium price for a product that produced dismal results.”
