[QUOTE="Winefly, post: 1499792, member: 46345"] Two cents worth from down under pick a powder preferably a slow one, even more preferable the one you are already using. start with the lowest load recommended and work up one grain at a time, three rounds of each, go out to the range shoot them, record which one gives you the best ES and the best group. Hopefully this will get you down to around the half three-quarter inch mark then it might be worth looking at seating. If the result you want is to shoot accurately you may find the 2800 - 2820 will give you very good accuracy or if your rifle allows it 2920 to 2950 may also be accurate. I found 2810 FPS to be my most accurate load at 6 mm at 100 m but I’m also pretty happy with 2935 fps giving me 8 mm groups. Something else to consider if you are reloading are you full resizing or neck sizing the brass? I found I get over Max velocity two grains under maximum recommended load so boom lookout! I also polish the throat every 50 rounds this can help! Best of luck [/QUOTE]
