Been working with a Winchester 70, SS/Synthetic in 30-06. It had been skim-bedded, pillars added and the fore end has been reinforced, barrel is floated too. I really wanted to shoot the Accubonds so I have tried 180's and 165's with RL22 and have been getting 2.5 MOA or worse. Tried working up to max loads and adjusted seating depth from lands to 0.050" away from the lands with the same results. It ticked me off because I brought some crusty factory loads with me to shoot last time and it shot them at about 1.5 MOA. I don't know what kind of load they were. Had an FC stamp and the bullet was a lead tip. It's an Elk gun that my brother-in-law shoots to about 500 yards. Would Bergers be worth a try? Any other thoughts on a better powder? I have some 200 gr Accubonds, try them? Thanks for any advice.
