You need to read your owners manual it tells you what ammo to avoid and that is one of them i believe. Mine has shot great, no problems here, people just need to take the time and read the manual.
Another thing to verify is whether your bolt spring is blue in color or not. The springs on the earlier models ha problems, and s&w change them out for the blue ones. If yours isn't blue send it in to s&w for a free warranty fix.
