I have never ordered by machine or lot, but know that you can buy it that way. I've often wondered why Lapua doesn't market their ammo along similar lines. As I said, I've never been able to get Lapua, Wolf or SK to group at 50yrds. SK would do well at 50 feet indoors. The Eley Club, Club Extra [now called Team and cost more] and even the Remington Eley have always been consistent. I keep checking out other brands, but still revert back to Eley when I want to get serious. All my rifles are older rifles, 52's,40x's and a 1973 Anschutz 54. Maybe that is why they like Eley. I haven't had a problem with the new EPS or automatch style bullets, They group as well as the older stuff in my rifles.
