Buy Lapua. Buy once, cry once. I have 200 pieces of 223 Lapua that was shot as 223, then necked down to 20 Practical, then back to 223. Don't have a clue how many times its been shot but still has tight primer pockets and works just fine. Personally, I would choose Hornady over Winchester. The last two bags of Winchester I bought were junk. JMO!
