Well i havent had the chance to shoot any .308 ammo from my X-Ray 51 yet simply because im still waiting to take possession of it! However i have made some starting loads from Redding Competition Bushing dies. I must say they are VERY nice dies.. HOWEVER done forget to buy the size bushing you want for the resizing die when you order it ( a mistake i made and didnt realize until i tried making some ammo). Well here is my 2 cents hope it helps.scotts1w said:I am researching .308 competition dies and am concerned about run out. What brands are others using that have generated good, results in Tactical Operations 51 platforms?
