I ran into this a few years back with 30-06 Corelokts. There was roughly 250fps difference. Federal and Winchester tend to be a bit closer to published values. Not dead on as that would be difficult to duplicate but reasonable anyway.

My son helps me set up sporting clays courses for a private club and then will help me work the shoot. He helps me instructing some as well and he traps a lot of big registered events. He tells me all the time, Dad, I know I'm supposed to respect my elders, but some of these folks are so ignorant its mind boggling.

Literally everyone who buys a leupold scope in Michigan. It's the bane of me. These dorks show up with a custom turret for the cds with info off the box and look you dead in the face and say they are good to 800-1k yards cause the dial goes that high. Thats who.

Well, the "certified" ones are 250ft/s slower. That's better than 400! Same 90+ ft/s spread. Avg this time was 2913. Fastest was like 2965 and was the first out the barrel, though a couple others were close. I sent them the data. All I got back was an email today telling me I had a box of ammo on the way originating in Minnesota somewhere, I think it was.
I'm guessing since I told them I found the ammo to be acceptable for my uses and thought it grouped well (8 of 9 were in about a 1 1/4" circle with 1 flier about an inch out in left field - 3rd shot of the string - not an extreme in velocity either way), they decided to reward me with a new box of it. I'll verify that one, too.
Knock 'em out. I'd be interested in seeing the numbers. 25 years ago I had a Ruger Tang M77 in 270 that shot really well with their 130 corelokts out to 440 yards. Most of the deer I killed then were 225 yards and under. I shot what I could afford and we killed a lot of deer. I wish I'd had the equipment to measure those loads.Well, the "certified" ones are 250ft/s slower. That's better than 400! Same 90+ ft/s spread. Avg this time was 2913.

The 30-06 I was zeroing was a Ruger ultralight with a 20" barrel. That thing kicked like a pack mule. You pretty much had to be mad at it to shoot it. Anyway I expected 100 fps or so deficit for the short barrel but nothing like i saw. I also remember the extreme spread was huge. Sort of like a "Box of Chocolates" you might say. You never know what you're gonna get.
On the other extreme 90 degrees plus is a regular occurrence at the start of our deer season and during our depredation hunting period. I've seen several examples of Hornady Superformance ammo stick in the chamber to the point the bolt needed to be opened with a dead blow mallet or assisted by a fiberglass rod down the barrel.
I'm a half *$$ gunsmith on good days and live in the equivalent of Bum Fire Egypt with no real gunsmith close so I often have folks bring rifles to me with the bolt stuck.

And here you have it, gents! They got the same 100ft/s extreme spread I did, but no problem with velocity, as everything is "in spec." Have no idea what "spec" is, but they say there is NO issue with the ammo other than the 1 that was 100 ft/s slower. And I guess that's still in spec. Show's over; draw your own conclusions.

I just happened to think about it. You guys realize what this means, right? Since my Xero is 400 ft/s slow, that means the 168gr Ballistic Tips I tested in my 20" custom .300 SAUM right after the .243 loads are actually making close to 3600 ft/s!!!
Definitely out of my specs! Meant to reply to other post before this one.I just happened to think about it. You guys realize what this means, right?

I'm not surprised in the least and what I was expecting.
Obviously you have never hunted in Montana. Hell we have guys here that buy new rifles, have the sporting goods store bore sight it and then they take it straight to the field hunting. Checking the info on the box against anything is asking way to much.......

They have also made it to South Carolina. Quite a few of them. "Mental Giants"
