In the process of re-stocking my 03A4. Time to do some relief work on the wood. This rifle always held it's zero even when hot with the old loose fitting stock. This morning , top 3 rnds were where they were supposed to be and then hits walked down as rifle warmed up. Wood seemed to have free movement to start then as things started to warm up it got tight as the dickens. That's what they make sanders for.
