You need to take off the cover and check the sear and hooks on your trigger. If you bent the flat a little off, and the trigger pin is canted to one side, there may not be enough "bite" for the sear to hold the hammer.
It may be catching the hammer at an angle that is just enough under the recoil of rapid fire to hold it, but under controlled fire it just doesn't slide enough.
Sometimes you can take a dremel and just smooth all the sliding surfaces. Sometimes you may have to adjust the angle on the hammer or sear to allow it to catch.
If the trigger pin is canted you may be able to weld up the the hole in the receiver and grind it to fit right.
This is a potentially dangerous situation both legally and physically.
Before doing any grinding make sure you check it really close. You can usually do this in the shop with the rifle secured to your bench.
See if you can work the trigger, hammer and sear manually. It should all work smooth, and when the hammer slides from the sear to the hooks it should all be in a alignment and smooth.

It could be that the carrier is not pressing the hammer low enough for the dissconnector to catch rather than the front sear hooks not holding. I had this happen on a Factory made milled reciever, the hammer and trigger holes were too far down from the top rails. To test, remove the top cover and release the hammer. Then while holding the trigger, pull the bolt to the rear without applying any down pressure on the carrier. If the disconnector (rear hook) doesn't catch easily every time you need to take some metal off of the top front face of the hammer. I would avoid grinding on the hook as it is easy to get it off angle. This might fix your problem without any welding.

I think I found the problem.The hammer spring seems to be bent.When the hammer is locked one leg of the spring moves forward and rubs between the trigger and disconnect.I think the alignment of the holes are fine ,everything engages evenly.This did only happen when shooting from the bench.The hammer goes down plenty far enough for the disconnect to catch.Hopefuly its just the hammer spring.I'll give it a try next week.Thanks for all the info.

That nasty lil ole wound wire spring can definitely shift positions if it has been bent.
Get a new one and make sure it isn't lifting up and binding somewhere. This could very well be your problem.
Glad to hear it isn't anything serious.

It was the trigger spring.Bent the leg so it would not come in contact with the disconnector and no more double rnds.Thanks for all the info.The good thing about having a problem with a rifle ,is by the time you fix it,you know it inside and out.
