The 6mm-284 is a better hot rod 6MM than the 6mm-06. And it works great in the Remington long action. Any of the barrels mentioned are very good tubes and have the potential to deliver great accuracy. But every one of them is its own little deal and you never really know what a given barrel is going to shoot or not shoot. If you go with a 9" twist, you can shoot the 105 Hornady A-Max - which is a great long range bullet for targets and medium big game - if your gun likes them. 70 gr. Ballistic Tips or Blitzkings are great varmint pills. I have also had several with a 10" twist and they shoot bullets from 55 gr. to 100 gr. well.
I wouldn't say better but I would say as good. I just finished a 6mm-284. Test firing starts when the weather moderates. If it looks like a Parker Hale Super, it's a stock I found on Ebay complete with a refurbished PH trigger. It took months to get this thing straight.....never again! Oberndorf M98 action with a Wilson barrel....all in all....decent. Regards, Rick.
