My brother has a new Ruger mini-30 stainless (older style). Out of the box, it worked flawlessly for a few hundred rounds. After cleaning and reassembly, an unusual problem has developed.

Every time the rifle is dry-fired, the action becomes *very* difficult to open - it's almost jammed solid. The action opens easily if it has not been dry-fired, and it still shoots perfectly. It did not do this when we first got it.

I assumed that it might be a lubrication problem, and added some grease to the likely spots but it did not help. The Ruger manual recommends only a light coat of oil on the working parts.

Any idea what can be causing this?

The action should be cocked,  bolt closed on an unloaded chamber, and the safety ON prior to dis-assembling the weapon.

Not real familiar with Rugers but,

When its easy to open without being dry fired it is because the hammer is cocked. After dry firing and trying to open the bolt you have to overcome the force of cocking the bolt.
The fact it seems jammed shut, is it possibly that the rifle was put back together incorrectly. If it was new I'd suggest maybe the parts need to wear a bit but you have a few hundred rounds through the rifle that should not be the problem. Maybe the trigger control group was taken apart and not put back together correctly?
If it was an AR15 I'd think maybe a blown primer or a piece of blown primer was stuck somewhere. Its funny where these things get wedged.
Since it has a few hundred rounds through it and should already be broken in I wouldn't force it open unnecessarily.

I've heard of several rifles that weren't assembled as you say that fell apart when they were shot.  It pays to READ the manual.<G>
