welcome sarg,
I have a 223 bull and have done just what you describe and it did help.
The tipp in the faq's is; remove the forearm and shoot it, if groups improve then it needs forearm work. Load, remove the forearm, shoot, put the forearm up against the barrel to open and load,, repeat.
There are several things that can be done listed in the faq's. I ended up useing a variation of the RTV bedding trick, I just used a narrow band of RTV silicon about an inch wide centered on the lug, and I used the 1/4" set screw inside the lug to maintain the same torque/stop on the screw.
With tips an tweeks, I'm shooting 1/2 MOA,,that's the fun part
