I have the 97D all blue model in 6mm BRM. It is a nice gun. I bought it unfired from an estate. It does shoot around 1" at 100 yards. The trigger is set at 1.5lbs. There are a few problems with reloading. 1. Brass and dies are only available from E. A. Brown. 2. In my case they offered only one load. when I called about it , I was told they were not in the bullet or powder business. 3. They do not offer case forming dies so all brass needs to be purchased from them. You could get forming dies custom. made. 4. There were no swivels studs. I like doing business with them and their prices are reasonable, but some of the people have an attitude.
The only difference I see between the ready made rifle and the custom is the finish on the receiver. If I was going to get a new one from E.A. Brown I would go with the ready made one.
