Be very very careful loading reduced loads with a slow burning powder like Re 22. If you want a reduced load refer to a good manual that lists reduced loads like the Speer manual for one. Light loads of slow burning powder are extremely dangerous. Never go below the manuals minimum load. I ruined a good gun when I first started reloading doing just that. Reduced loads of some powders explode instead of burning. I was using 4320 when I had my mishap and that is not even a real slow burner. It froze up the action and created exessive head spacing and I had to rebarrel the gun. The load Vap mentioned above may be a very safe load I don,t have a manual handy right now. I just like to save someone else from bad expierences.
