Update #2: I've had my Sako VLS .223 to the range four times since I changed the extractor spring and refined the extractor claw and, I'm happy to say, it's still ejecting spent cases perfectly. I am very happy with it now and my previous thoughts of selling it have passed. It is easily shooting MOA but I need to read cross winds a little better. I still haven't experimented with loads and projectile weights as I still have 55gn Hornady Varmint SP pills being pushed out of the barrel by a starting load of ADI AR2206H. My barrel has a 1 in 8 twist so I feel my current, and very pleasing, group size will only improve with a little load development. I still 'scratch my head' wondering why Sako/Beretta couldn't have got the ejection of cases right in the first place. I know it is only a small percentage of rifles exhibiting this poor ejection trait but it seems so fixable.
