What loads (brands) are you shooting in it?

Ditto with matouse3. Those crappy Winchester Wildcats will do that every time.

Yeah, i'm with shane. Clean that bugger.

just take it to a local gun nut that you trust or gun dealer they will fix it or thell you whats wrong

Another point - this hinges on proper cleaning as well: since we are talking about a semi-automatic gas- operated firearm, FAILURE TO CLEAN THE GAS PORTS PROPERLY MAY RESULT IN A MALFUNCTION. In this case, the ports may be stopped up with dirt, crud and corruption, even though the gun looks spotless. The effect is that the action will cycle faster than intended, slamming forward on the properly ejecting empty case and jamming the gun up. It is also not uncommon to eject the casing and fail to load the next round, since the action is moving faster than the mechanical magazine spings can push. This goes for reloaders as well - the same thing will happen if an individual says "Hey, watch this", and promptly overloads a few rounds expecting the weapon to function the same way. It's like putting higher octane gas in your car, there's more power transfer with the added fuel; so the gasses try to blast out of the gas ports and cause the weapon to cycle really fast. Take a small drill bit (NOT IN THE DRILL) and roll it between your fingers to clean out the ports periodically. YOU ARE ONLY REMOVING DIRT AND GUNK HERE, NO STEEL CHIPS. If you open the holes up larger than they were originally drilled, there will be less pressure working on the action, and the gun may fail to lock up or shut properly (and most guns won't fire if they aren't shut). THIS IS BAD. And if you feel uncomfortable with any operation on a gun, take it to your local smith. They'll thank you for not destroying or altering anything.
